1) SLM-200, 20, 210: No AR coating.
Please refer to the table for the available AR coating range.
2) Response times are typical values and are not affected by frame rate.
Tr: The time required for the phase to change from 10% to 90% when changing from 0 to 1023 bits (2π rad.) at room temperature (25°C)
Tf: The time required for the phase to change from 90% to 10% when changing from 1023 (2π rad.) to 0 bit at room temperature (25°C)
3) 0th order diffracted light. The reflectance varies depending on the specified wavelength range.
4) Power handling is not guaranteed.
Depending on the specifics of the laser oscillator you use, damage may accumulate and significantly shorten the product's lifespan.
SLM-200, 20, 210: CW 1550 nm, beam diameter 2 mm
SLM-250: Max. 10 mW/cm2: @365 nm, 24H/day continuous operation
SLM-250: Typ. 40 mW/cm2: Peak power @355 nm, pulsed laser
SLM-300, 30: CW @1064 nm
SLM-310: CW 6.5mm@1070nm
5) We cannot guarantee against defects in LCD pixels.
6) DVI: 10-bit using RGB 8-bit, 3 colors
