LBTEK's spatial light modulators are reflective phase-type devices with a very broad spectral range, covering 420-1700 nm depending on the model, making them suitable for various optical application scenarios. They also feature high resolution, supporting 2048×2048 resolution, enabling clear light field modulation effects. Additionally, the product has a refresh rate of 60 Hz, ensuring real-time and stable light field modulation. The damage threshold can reach up to 1000W/cm², allowing stable operation in high-intensity light environments; the optical utilization efficiency is as high as 90±5%, effectively reducing light energy loss and further improving device efficiency. The mechanical housing surface is equipped with M6 threaded holes for easy installation in free space; it also includes two adjustment knobs for effective horizontal and vertical alignment of the target surface, enhancing usability.

Compared to the SLM-P2020-VISIR1, the SLM-P2020-VISIR2 has a thicker light valve, providing a higher maximum phase modulation capacity, making it more suitable for wavefront correction and large-angle beam deflection scenarios. For wavelengths of 900-1100nm, the SLM-P2020-VISIR1 is recommended, while for wavelengths of 1500-1700nm, the SLM-P2020-VISIR2 is recommended.
