The thickness of the coating
layer is not equal on the lens, and the long wave pass
cutoff range shows a gradual change result on the lens.
Commonly used in cutoff of
grating multistage diffraction light, putting before CCD
of optical fiber spectrometer.
The quartz substrate was coated by ion sputtering to
achieve minimum autofluorescence and high laser damage
threshold.
CNI provide
standard model size is 41.4mm×9.5mm×1mm. |
