Product description
This dual-bandpass optical filter is designed for applications in machine vision and laser systems, enabling simultaneous transmission of visible light (400-680 nm) and 905 nm infrared signals. It effectively meets the technical requirements for co-existing imaging and laser ranging on a single optical lens, minimizing the need for multiple filters. With high transmittance and excellent out-of-band blocking, this filter enhances sensor performance by improving signal-to-noise ratios and reducing interference.
Key Features
- High transmittance of ≥85% in the visible band and ≥86% at 905 nm for clear imaging and stable signal reception.
- Optical density OD 3 for effective blocking of unwanted wavelengths, reducing stray light and enhancing image quality.
- Manufactured from high-quality BK7 optical glass for low birefringence and consistent optical performance.
- Custom dimensions, shapes, and thicknesses available to meet specific application needs.
- Suitable for OEM, ODM, and OBM projects to align with diverse customer requirements.
