The 420–580nm SWP Optical Filteris designed for applications
requiring selective transmission of visible short-wavelength
light and suppression of longer wavelengths.
The filter uses an optical glass substrate with a precision
multilayer coating to provide controlled spectral transmission.
Light within the specified 420–580nm range is transmitted,
while wavelengths above 580nm are effectively blocked.
This makes the filter suitable for optical imaging, analytical instruments,
scientific equipment and other systems requiring wavelength separation or spectral control.
The filter is designed for transmission within the 420–580nm
wavelength range, making it suitable for visible-light optical systems.
Wavelengths above580nmare effectively blocked to
reduce unwanted long-wavelength light reaching the optical detector or imaging system.
High-quality optical glass provides a stable substrate for
precision optical coating and integration into optical assemblies.
The precision multilayer coating provides controlled
spectral transmission and stable optical performance.
The SWP design provides a defined transition between
the transmission region and the blocked long-wavelength region.
Round and square configurations are available,
with custom dimensions available for OEM optical systems.
