Revenues were $16.2 million, including $9.2 million of TFE revenues and $7.0 million of Photonics revenues. TFE revenues consisted of one MATRIX PVD system for advanced semiconductor packaging, as well as HDD upgrades, spares and service. Photonics revenues consisted of $3.8 million of product sales and $3.2 million of research and development contracts. In the first quarter of 2020, revenues were $18.8 million, including $8.0 million of TFE revenues which consisted of upgrades, spares and service. Photonics revenues consisted of $5.9 million of product sales and $5.0 million of research and development contracts.
TFE gross margin was 23.1%, compared to 44.0% in the first quarter of 2020. The decline was primarily due to product mix, given the lower-margin contribution from the first MATRIX PVD system in the first quarter of 2021 and the higher mix of higher-margin HDD upgrades in the first quarter of 2020. Photonics gross margin was 13.1%, compared to 42.8% in the first quarter of 2020. The decline was primarily due to lower margins on research and development contracts resulting from higher costs related to additional work needed in order to complete the integration of our camera into the IVAS platform as we neared the end of the development program. Consolidated gross margin was 18.8%, compared to 43.3% in the first quarter of 2020.
R&D and SG&A expenses were $9.6 million, compared to $9.3 million in the first quarter of 2020.
Order backlog totaled $43.1 million on April 3, 2021, compared to $46.9 million on January 2, 2021 and $87.2 million on March 28, 2020. Backlog at both April 3, 2021 and January 2, 2021 did not include any 200 Lean® HDD systems. Backlog at March 28, 2020 included two 200 Lean HDD systems.
The Company ended the quarter with $53.6 million of total cash, cash equivalents, restricted cash and investments and $97.2 million in tangible book value.
