LBTEK's Spatial Light Modulator (SLM) is a reflective Phase type, with a very broad spectral range that can cover 420-1100 nm depending on the model, making it suitable for various optical application scenarios. At the same time, it features high Resolution and supports a 2048×2048 Resolution, delivering clear light field modulation effects. In addition, the product's refresh rate reaches 60 Hz, ensuring the real-time performance and Stability of light field modulation. Its Damage Threshold can reach up to 1000W/cm², allowing stable operation under high-intensity light environments; its optical utilization efficiency is as high as 90±5%, effectively reducing optical energy loss and further improving device efficiency. The surface of the Mechanical Housing is provided with M6 Tapped Holes for convenient installation and use in free space; it is also equipped with two Knurled Knobs, which can effectively achieve horizontal and vertical adjustment of the target surface, enhancing convenience of use. Among them, the SLM-P1910HR-VIS model uses a short flat cable (non-magnetic version), the SLM-P1919-VIS is a Monolithic Spatial Light Modulator (SLM) with integrated driver, and the remaining models use long flat cables (magnetic version)
Note: When placing an order, please specify the wavelength of the Laser used so that calibration can be performed directly at the factory!!!

High-LIDT liquid crystal Spatial Light Modulator (SLM) is prone to heat accumulation when used in strong laser scenarios, which in turn causes liquid crystal performance drift, Wavefront Distortion, and even optical damage. The accompanying water-cooled heat dissipation module can efficiently dissipate the device's operating thermal load, suppress modulation performance degradation and optical Distortion induced by heat accumulation, enhance the device's laser damage resistance, and ensure Phase/Amplitude Modulation accuracy. If you have any other questions, please contact LBTEK technical support.
