Narrow and wide bandpass filters centred on your target wavelength. Every optical filters part is made to your drawing, so dimensions, material grade, coatings and finish are all specified by you and verified in-house before shipping.
Overview
Bandpass Filter is produced from Coated optical glass filters — longpass, shortpass, bandpass, notch, dichroic and neutral density — cut to your aperture. We machine, finish and inspect the part under one roof, which keeps tolerances, surface quality and documentation consistent from prototype through to production quantities.
Typical applications
Customers use this component across photonics, semiconductor, biomedical and instrumentation work. Whether it goes into an optical path, a sensor stack, a diagnostic device or a piece of process tooling, the geometry and surface specification can be tuned to your exact requirement.
How we make it
Depending on the design we combine femtosecond laser ablation, CNC ultrasonic machining, precision dicing, optical polishing, thin-film coating and thermal or anodic bonding. A design-for-manufacturing review checks feasibility before cutting, so problems are caught on the drawing rather than on the shop floor.
