490–1100nm Reflective Optical Filter
The 490–1100nm Reflective Optical Filter is designed to efficiently manage light across
the visible to near-infrared wavelength range. It features a reflective
optical design combined with a high-precision multilayer thin-film coating
applied to a high-quality optical glass substrate, ensuring stable spectral
performance and long-term reliability.
The filter provides high transmission within the 490–1100nm working
range while delivering high reflectivity outside the passband,
resulting in low optical loss and excellent wavelength separation.
The use of optical-grade glass ensures superior surface quality,
coating adhesion, and environmental durability.
To meet diverse application requirements, custom sizes, shapes,
thicknesses, and wavelength specifications are available.
This filter is well suited for machine vision, optical imaging,
spectroscopy, medical devices, and industrial optical systems
where consistent and precise optical performance is required.
