1) 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℃.
2) Zero-order reflection.
Depending on specified wavelength range.
3) Specification on the defect pixels are no object.
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.
