STANDARD IR LONG PASS FILTERS
Long wave pass filters are 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 filters will withstand normal cleaning and handling associated with any high-quality optical component.
For your convenience and economy, we offer the filters in three standard sizes: 12.5mm, 25mm and 50mm dia. However, we can produce custom sizes and shapes, as well as custom optical characteristics. Contact our technical sales department for a quotation.
We also offer long pass filter in the UV and visible wavelength ranges, including steep-edge long pass filters.
BENEFITS
- Useful for isolating broad spectral regions
- Constructed of hard, durable first-surface coatings
- Available in standard and custom wavelengths
COMMON APPLICATIONS
- Order sorting
- FTIR spectroscopy
- Thermal imaging
