Take Control of Light
Spatial Light Modulator for laser processing (500W durable model)
SLM-310-G Preliminary
SLM-310-G with significantly improved higher input power durable up to 500 W at 515 nm (green light). This product combines santec LCOS technology with a highly durable specialty liquid crystal and a proprietary water-cooling design to dissipate heat generation for maximum performance. The SLM-310-G water-cooling LCOS based SLM utilizes a (V)15.36mm x (H)9.6mm, small diagonal 0.72 inch LCOS panel size with a pixel resolution of WUGA (1920 x 1200) 2.3 Mega-pixels, and It has a superior 10 bit (1024 gray level) phase resolution exceeding the standard commercially available 8 bit (256 gray level). Using green lasers has a significant advantage over near-infrared lasers for laser processing because of excellent absorption of green light in numerous metals. Using high power durable SLMs at 515 nm enables new complex processes such as software programmable dynamic beam shaping, beam direction correction and multiple beam splitting and focusing using computer-generated holograms, which can not be achieved using current laser processing methods such as a Galvano-scanner.

1) Specification on the defect pixels are no object.
2) Zero-order reflection.
Depending on specified wavelength range.
3) Response time is a typical value and is not affected by frame rate.
Tr: Rise time between 10% and 90% levels in a phase change of 0 to 1023 bit (2π rad.) at 25℃.
Tf: Fall time between 90% and 10% levels in a phase change of 1023 to 0 bit (2π rad.) at 25℃.
4) The value is not guaranteed.Depending on the conditions of the laser oscillator used,
the product's life may be significantly shortened due to accumulated exposure time.
5) Supports NPT standard using attached conversion adapters.
Application
■Laser Welding Simulation
This simulation demonstrates the effectiveness of laser welding through precise beam profile control. By optimizing the beam intensity distribution, several improvements in welding quality and productivity can be expected, including (1) reduced spatter droplets, (2) fewer bubbles and voids within the weld, (3) minimized weld marks, and (4) increased welding speed.
