Products Description
45° Dichroic Longpass Filter 570–700nm | Tave > 95%
The OPTOStokes 45° dichroic longpass filter provides precise spectral separation, delivering average transmission greater than 95% across the 570nm to 700nm waveband while efficiently blocking unwanted wavelengths from 400nm to 550nm down to below 1%. Designed for demanding optical optical layouts operating at a 45 degree angle of incidence, this high-performance dichroic filter maximizes signal throughput and minimizes optical crosstalk in sensitive detection channels.
