Standard long wave pass optical filters

Long wave pass optical filters provide a sharp cut-off below a particular wavelength. Often used for order sorting, they isolate broad regions of the spectrum, simultaneously providing high transmission of desired energy, and deep rejection of unwanted energy.

Constructed of hard, durable first-surface dielectric coatings on optical-quality IR-transmitting substrates, these long wave pass optical filters will withstand normal cleaning and handling associated with any high-quality optical component.

For your convenience and economy, we offer the filters in two standard sizes: 25mm and 50mm dia. However, we can produce custom sizes and shapes, as well as custom optical characteristics.

We also offer long pass filter in the UV and visible wavelength ranges, including steep-edge long pass filters.
