Thank you, Sam. First, I would like to mention that much of the information we are discussing during this call is also included in a press release issued earlier today and in our 10-Q filed with the SEC. I encourage you to visit our website at lightpath.com and specifically the section titled Investor Relations.
Now on to my remarks pertaining to the fiscal 2021 second quarter and half year ended December 31, 2020. Sam's remarks covered a lot of our financial performance, so I will be specifically discussing some of the key performance areas.
Revenue for the second quarter of fiscal 2021 was approximately $9.9 million, up 4% sequentially from $9.5 million in the first quarter of 2021 and up 3% from $9.6 million in the second quarter of fiscal 2020, when we had about $0.5 million in holdover revenue from the first quarter 2020. Revenue for the first half of fiscal 2021 was approximately $19.4 million, an increase of $2.3 million or 13% as compared to $17.2 million in the same period of the prior fiscal year. Infrared product revenue was $4.8 million in the second quarter of fiscal '21 or 48% of the total revenue, down from $5 million or 52% in the second quarter of fiscal 2020. Visible precision molded optics, or PMO products, revenue in the second quarter of fiscal 2021 was $4.7 million or 48% of the total, up from $7.7 million or 39% of the total in the second quarter of fiscal 2020.
The balance of our revenues for the second quarter was $372,000 from specialty products and nonrecurring engineering projects, which vary greatly from quarter-to-quarter, but are substantially smaller contributors to the consolidated revenue. Revenue from this group in the prior year were $885,000.
With respect to our margin profile, generally speaking, PMO products are smaller and almost entirely molded. So we have faster turnaround time, higher-volume applications and more automated processing. These products also are generally low in price. We historically have a margin averaging in the 40s to 50 range. Of our 2 primary revenue reporting groups, PMO is the smaller group with a higher margin. With the higher volumes and margins, you can determine -- one can determine that our average unit selling prices will trend lower than with the infrared groups. The infrared product group represents a larger and faster-growing market opportunity. Infrared margins have historically been in the 20% to 30% range, and depending on the revenue mix in any particular period under review, our ASPs can vary, so we do not believe that this is a meaningful performance analytic.
Instead, we encourage investors to focus on our revenue and gross margin as a percentage of the revenue over the long term, not necessarily on a quarterly basis, since we are relatively a small company where order completions can influence our results in any particular short-term or quarterly period. In the first quarter of 2021, our top line growth was much higher than a traditional quarter due to the holdover revenue from the prior year period, where revenues were pushed from the first quarter 2020 to the second quarter 2020.
Similarly, the second year -- second quarter year-over-year comparison masked our second quarter 2021 growth, since the second quarter 2020 included the holdover revenues from the first quarter 2020. Our margin -- our gross margins can similarly fluctuate depending on order completions, product groups that dominate the quarter and other important operational issues. As Sam mentioned, we have a significant amount of new product launches coming online, which generally have much lower yields and efficiencies, which reduce our gross margin on the units shipped in that quarter.
When the product line is bolstered with fine-tuning, we will increase volumes and output, which will elevate gross margins to a more normalized basis. Many of our product lines coming into production volumes in the second quarter 2021 are from our molded infrared lens family of products, which use our proprietary, internally developed BD6 materials. These will come in on the higher end of the margin range. Increases to our margin will be realized within this category as volume growth and efficiencies improve. Gross margin as a percentage of revenue was 38% for the first half of fiscal 2021 compared to 37% for the same period of the prior fiscal year. So we are moving in a positive direction, even though our second quarter 2021 margin were impacted by a fair amount of product launch dilution.
As we have discussed, we have new production lines being introduced, which have low initial outputs. These will increase and with it, so will the margins. Some of these new lines are converting all the lower margins germanium lenses to our new BD6 material, which also will lend to higher gross margins. At the same time, we continue to produce more lenses overall. Total production for the product lines increased to 1.1 million lenses in the second quarter, up from 900,000 lenses in the second quarter of last year. In the first 6 months of fiscal 2021, we shipped 2.4 million lenses, up from 1.5 million lenses in the prior year period.
Moving on to operating expenses. During the second quarter of the fiscal 2021, total operating expenses was approximately $3.6 million, an increase of about $700,000 or 24% as compared to the $2.9 million in the same period of the prior fiscal year. The increase is primarily due to $400,000 of nonrecurring additional compensation to the company's former CEO and higher SG&A for a moderate increase in headcount and costs associated with operational improvement projects.
New product development costs increased by approximately $61,000 or 13%, which was needed to address the demand for advanced optical designs. Partially offsetting these increases was limited travel and marketing expenses from the COVID-19 restrictions, net of pandemic-related increases of cleaning and safety expenses. Operating expenses for the second quarter of the fiscal 2020 was also reduced by a net gain on disposal of property and equipment of $79,000, which did not repeat in the second quarter of fiscal 2021. Our consolidated corporate income tax in the U.S. is shielded by our net operating loss forward benefits of approximately $74 million on December 31, but we must pay income tax in the countries of certain foreign subsidiaries.
Second quarter 2021 income tax expense was approximately $241,000 compared to approximately $322,000 for the same period of the prior fiscal year, primarily related to income taxes from the company's operation in China. Income tax for the second quarter included Chinese withholding taxes of $200,000 associated with intercompany dividends declared by the company's Chinese subsidiary in December of 2019. Net foreign currency translation gains, due to changes in the value of the Chinese yuan and the euro against the U.S. dollar, was $77,000 in the second quarter of fiscal '21 compared to $119,000 in 2020, with no impact on the earnings per share in either period.
Net loss for the second quarter 2021 was $147,000 or $0.01 per share compared to a net income of $769,000 or $0.03 per share -- earnings per share for the second quarter of fiscal 2020. For EBITDA, a non-GAAP measure which we believe provides important insight into our performance and progress, we had a positive EBITDA of approximately $1 million in 2021 as compared to $2 million for the second quarter of fiscal 2020. This decrease was primarily due to the low operating income from lower gross margin and increased SG&A, primarily, again, for the $400,000 of nonrecurring additional compensation for the former CEO, and to a lesser extent, the increase in new product development expenses.
Again, looking at our longer-term progress, which is more meaningful, EBITDA for the first half of fiscal 2021 was approximately $2.4 million or $2.8 million, excluding the onetime nonrecurring departed executive additional compensation, as compared to $1.8 million for the first half of fiscal 2020.
Moving to the balance sheet and cash flow related items. Capital expenditure was $1 million in the second quarter of 2021 and $2.2 million for the first half of the year, up from under $1 million in the second quarter of 2020 and $1.2 million for the first half of the fiscal 2020. Given that we have been running at near capacity, and our backlog continues to grow, we will increase our expected capital expenditures for the year to come within a range of $2.5 million to $3 million for the year, up from the $2.0 million vicinity. It is important to note, however, that the recognition of capital expenditures is based on the dates of invoices, and in some cases, prepayments. And often, these are delayed between the timing of decision and order, to when the capital expenditure is booked and when the equipment is received and brought online.
Meanwhile, net cash provided by operation was $1.5 million for the first half of fiscal '21, up from $938,000 in the prior year period. Total debt, including financial leases, was $5.7 million, which was reduced approximately by $246,000 in the first half of fiscal '21 from $6 million at the beginning of the fiscal year. This represents a 4% reduction year-to-date. Our cash balance on December 31, 2020 was $5.3 million, down modestly from a $5.4 million at the beginning of the fiscal year even though we reduced debt amid significant investment to increase our production capacity to deliver future revenue growth and increased cash flow.
Finally, on to our backlog. As of December 31, 2020, LightPath's total backlog was $23.8 million, an increase of 6% from $22.6 million as of December 31, 2019 and an increase of 9% from $21.9 million as of June 30, 2020. Our December 31, 2020 backlog is the highest level in the company's history. It should be noted that it is natural for our backlog to fluctuate during the year because of the timing of such bookings of large orders and annual renewals.
With this review of our financial highlights and recent development concluded, I will now turn the call over to the operator so that we may begin with our question-and-answer solutions (sic) [ session ]. Thank you.
