The demand for wavelength-selective optical components continues to grow in machine vision, imaging and optical sensing systems. To meet these requirements, we provide a 650–750nm Bandpass Optical Filter designed for applications requiring controlled transmission in the red to near-infrared wavelength region.
The filter features a typical 700nm center wavelength and 100nm FWHM bandwidth, providing transmission across the 650–750nm spectral range.
The optical filter provides a peak transmission of ≥90% within the passband.
This design helps maintain useful optical signals while
reducing unwanted wavelengths outside the target spectral range.
The filter also provides OD4 / OD5 blocking over
specified wavelength regions from 400–650nm and 750–1100nm.
The 650–750nm bandpass region is suitable for a range of optical applications, including:
· Machine vision
· Industrial imaging
· Optical sensing
· Photoelectric detection
· Spectral imaging
· Optical measurement
· Camera systems
By selectively transmitting the required wavelength range,
the filter can help improve spectral selectivity in optical detection systems.
Depending on the application, the filter can be manufactured
using optical glass, BK7 or fused silica substrates.
Custom dimensions and optical specifications are
also available for OEM and optical system integration.
Different optical systems may require different filter dimensions
and spectral characteristics. We can support customization
according to customer drawings or technical specifications,
including size, substrate, center wavelength, bandwidth,
transmission and blocking requirements.
For projects requiring a 650–750nm bandpass filter or 700nm optical filter,
please provide your required size, thickness, quantity and application.
Our engineering team can review the specifications and recommend a suitable configuration.
