1436Hz frame rate - Pure Phase Liquid Crystal (SLM)

Optics company focuses on simulating the design, development, and manufacturing of pure phase spatial light modulators, with 40 years of production experiencespatial light modulatorhistory. Recently, the company has developed a product with1436HzFrame ratePure phaseliquidCrystal spatial light modulator with a resolution of 1024x1024 pixels. At present, the frame rate of spatial light modulator products on the market is basically at the level of 60Hz frame rate. The emergence of this product can provide strong support for a wide range of scientific research applications. By using simulated data addressing technology, excellent functionality can be achieved.

Meadowlark Optics' liquid crystal on silicon (LCoS) spatial light modulators (SLMs) are designed specifically for pure phase applications and include analog data addressing with high refresh rates. This combination can provide users with both high-speed response time (<1ms) and high phase stability (up to 0.2%) products. 1024="" ×="" 1024="">1ms) and high phase stability (up>SLM modulatorSuitable for applications that require high-speed, high diffraction efficiency, low phase ripple, and high-power lasers.

1436Hz frame rate pure phase liquid crystal spatial light modulator (SLM) product features:

Feature 1High LCD response speed (<1ms), high refresh rate>1ms), high refresh rate>

The 1024 × 1024 SLM has an incredible liquid crystal response time of 0.965ms (Rise time), 0.97ms (Fall time) @ 532nm (0-2pi, 10-90%), Operating at a typical room temperature of 26 ℃.

Feature 2:High diffraction efficiency (Up to 98%)

The 1024 × 1024 spatial light modulator can provide both regular version (97.2% fill factor) and dielectric mirror coated version (100% fill factor). The reflectivity of SLM coated with dielectric film can reach 100%, and the first-order diffraction efficiency can reach 98%.

Feature 3:High phase stability (0.2-1.0%)

The R&D team of Meadowlark Optics combined traditional analog driving solutions with some new proprietary technologies and applied them to this high-speed liquid crystal spatial light modulator, effectively achieving unprecedented high phase stability of 0.2-1.0% at high refresh rates.

Feature 4:Datong smooth surface, capable of withstanding higher laser power (17.40 x 17.40 mm)

The 1024x1024 spatial light modulator uses 17 x 17 µ m pixels, resulting in an effective area of 17.40 x 17.40 mm for the light aperture. For customers with a demand for high-power lasers, higher power application requirements can be achieved.

Feature 5:Can automatically perform linear calibration at any wavelength

The control software of this SLM model has been upgraded to automatically perform distortion calibration and linear calibration for different wavelengths, generating corresponding wavefront calibration files (WFC) and linear calibration files (LUT).
