MSE PRO™ BK7 Long Wave Dichroic Plate Beamsplitters
MSE supplies offers BK7 Long Wave Dichroic Plate Beamsplitters. They allow NIR light to pass through and reflect visible light at 45 incident angle. They have a very steep transition between the region of transmission and reflection. They have a hard and dielectric coating using interference rather than absorption to isolate the spectral bands. Unlike colored glass filters the cut-off wavelength will shift to shorter wavelengths with an increase in angle of incidence.
MSE Supplies can offer a variety of optical components. Please contact us for customization or bulk orders.
