Overview of Edge Filters
As a trusted manufacturer of optical filters, we specialize in custom edge filters, including longpass and shortpass filters. These precision components are essential for applications requiring selective wavelength transmission, such as imaging, spectroscopy, and medical diagnostics.
Understanding Longpass and Shortpass Filters
Edge filters are categorized into two types:
Longpass Filters: These transmit longer wavelengths while reflecting shorter ones, ideal for applications needing precise spectral separation.
Shortpass Filters: These transmit shorter wavelengths and reflect longer ones, with the cut-off wavelength (50% transmission point) being a critical parameter.
Spectral Characteristics
The primary difference between longpass and shortpass filters lies in their transmission ranges:
Longpass Filters: Allow wavelengths above a specified cut-off (e.g., 590nm, 600nm, 650nm, 700nm) to pass, blocking shorter wavelengths.
Shortpass Filters: Permit shorter wavelengths to pass while blocking longer ones, commonly used in UV detection or infrared rejection.
Applications of Edge Filters
Our edge optical filters are designed for diverse industries:
Longpass Filters: Widely used in fluorescence microscopy, Raman spectroscopy, astronomy, environmental monitoring, and biomedical imaging for selective long-wavelength transmission.
Shortpass Filters: Ideal for UV spectroscopy, imaging systems, and hot mirrors, where they block unwanted infrared radiation to reduce distortion.
