The 610–1100nm Long Pass Optical Filteris a spectral selection component
designed to transmit wavelengths from610nm to 1100nmwhile
suppressing shorter wavelengths.
The filter features a610nm cut-on wavelength, making it suitable
for optical systems that need to reduce shorter-wavelength light
while allowing longer-wavelength visible red and near-infrared light to pass.
The typical blocking region is400–600nm.
The optical filter uses a high-qualityoptical glass substratewith a
precisionoptical thin-film coatingto achieve controlled spectral filtering and stable optical performance.
Its broad610–1100nm transmission bandmakes it suitable for
a variety of imaging, sensing and optical measurement applications.
The filter is designed to begin transmitting around the specified610nm cut-on wavelength.
The filter provides transmission across the specified610–1100nmwavelength range.
The filter is designed to block shorter wavelengths,
with a typical blocking range of400–600nm.
High transmission within the passband helps reduce
unwanted optical loss in the desired wavelength region.
Precision optical thin-film coating provides controlled
spectral performance and supports coating durability.
High-quality optical glass provides a stable substrate for optical coating and precision filtering.
A smooth surface and high uniformity support integration into imaging and sensing systems.
Custom wavelengths, dimensions, shapes and thicknesses
are available for OEM and specialized optical systems.

A long pass filter is designed to transmit wavelengths longer
than its cut-on wavelength while blocking shorter wavelengths.
For this product:
Cut-On Wavelength: 610nm
Transmission Band: 610–1100nm
Typical Blocking Range: 400–600nm
This spectral response allows the filter to reduce unwanted
shorter-wavelength light while transmitting longer-wavelength visible red and near-infrared radiation.
The filter can therefore be used when an optical system
needs to isolate longer wavelengths for imaging, sensing or measurement.
The610–1100nmtransmission band covers a useful range
from the red visible region into the near-infrared spectrum.
Blocking shorter wavelengths from the typical
400–600nmregion helps reduce unwanted spectral components.
High transmission within the passband helps maintain
optical efficiency in the desired spectral region.
The filter is designed for low insertion loss within the pass
band according to the specified optical configuration.
The optical thin-film coating provides controlled spectral filtering and stable performance.
A smooth and uniform optical surface supports consistent
performance in imaging and sensing applications.
The 610nm long pass filter can be used to control spectral
input in machine vision systems, particularly where longer wavelengths are preferred.
The broad transmission extending to1100nmmakes the filter suitable for near-infrared imaging systems.
Can be integrated into NIR detection systems requiring suppression of shorter wavelengths.
Suitable for sensors requiring controlled transmission of red and near-infrared wavelengths.
Can be used in camera and imaging systems requiring long-wavelength spectral selection.
Suitable for analytical and optical instruments requiring long-pass spectral filtering.
The filter can help reduce unwanted short-wavelength light reaching imaging detectors.
Suitable for optical research, testing and laboratory measurement systems.
