NANO PRO™ Long Pass Filters, Ø1"
NANOSSR offers Ø1" Long Pass Filters. The substrate materials of the color filters inherently have different absorption and transmission properties across the spectrum. The are often used as long-pass and band pass filters. It should be noted that the boundaries between passing and blocking wavelengths are less sharp than most coated filters, although peak transmission is often considerably higher.
NANOSSR can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
