LP505 Long Pass Filter | 60/40 Surface Quality, 1.0mm & 1.1mm Thickness

LP505 Long Pass Filter | 60/40 Surface Quality, 1.0mm & 1.1mm Thickness

The LP505 Long Pass Filter from OPTOStokes is a high-precision Interference Filter engineered for sharp spectral edge performance and reliable long-term operation. As part of our extensive Longpass Filters portfolio, it blocks ultraviolet and short visible wavelengths from 350 nm to 500 nm with transmission below 1%, while delivering over 90% transmission across the 510 nm to 1100 nm band. Designed for both R&D prototyping and OEM integration, this filter ensures consistent spectral output for demanding optical detection and imaging systems.

Technical Specifications

Typical Applications

This LP505 long pass filter is widely deployed across precision optical systems. Primary use cases include spectral calibration equipment, laser beam separation and stray light rejection, machine vision inspection stations, fluorescence detection setups, and analytical instrumentation. Its steep spectral edge and high transmission efficiency make it suitable for both benchtop laboratory instruments and integrated industrial optical assemblies.

Customization & Service

OPTOStokes supports full dimensional and spectral customization for this filter. We manufacture circular, square and custom-shaped substrates, and offer optional mounting ring assemblies for simplified system integration. Our advanced Thin Film Coating processes ensure excellent batch-to-batch consistency and environmental durability. We maintain a broad in-stock selection of standard sizes for fast delivery, and provide reliable, predictable lead times for all custom orders with guaranteed quality standards.
