Shortpass filter

At Optical Filter Shop, we design our long wave pass (LWP) filters to separate the light spectrum into reflected and transmitted components. Also known as an edge filter, LWP filters contain either a cut-on or cut-off slope that defines the transition between a highly reflective and a highly transmitted region. We use a technologically advanced sputtering method to apply multi-layer coatings to our filters, providing superior durability and stability in the highest-output light settings.

Optical Filter Shop stocks a wide variety of LWP filters for performance in the visible (VIS), ultraviolet (UV), infrared (IR) and near-infrared (NIR) wavelengths. We can customize our LWP filters to match your application’s specific wavelength and angle requirements to deliver the targeted blocking you need. In addition to our innovative coatings, we can customize our LWP filters by cutting them into various shapes and sizes.
