PRODUCT FAMILY
Transmission Gratings
Transmission diffraction gratings separate wavelengths as light passes through the grating substrate.
They support compact spectrometers, wavelength analysis and teaching systems where groove density, diffraction efficiency and operating order determine resolution.
