Custom optical filters · infrared thin films
Build the optical response your system requires.
Bodian Optical supports engineering inquiries for optical filters, infrared filter families and thin-film coating projects. Start with your spectrum, substrate and mechanical requirements.
Filter families
Start from the function.
Choose the closest optical function, then refine the specification around your source, detector and working environment.
Bandpass filters
Define center wavelength, bandwidth, transmission and blocking for a targeted spectral window.
View pathwayLongpass filters
Transmit wavelengths beyond a selected cut-on point while managing the rejected region.
View pathwayShortpass filters
Pass the shorter-wave region and specify the cut-off transition and blocking band.
View pathwayInfrared optical filters
Explore narrowband, broadband, longpass, shortpass and anti-reflection filter pathways.
View pathwayOptical coating services
Start with a substrate, sample or drawing and describe the optical response you need.
View pathwayFTIR beamsplitters
Discuss operating range, substrate material, geometry and instrument integration.
View pathwayCustom filter brief
A useful RFQ begins with the optical problem.
Share the design inputs you already have. A complete drawing is helpful, but a clear spectral target and application context can start the review.
Plan a custom filterSpectrum
Target band, center wavelength and bandwidth
Blocking
Rejected range and optical density requirement
Geometry
Angle of incidence, clear aperture, size and tolerance
Material
Substrate preference and operating environment
Application pathways
Connect the filter to the system.
Application context helps frame spectral, material and environmental requirements before technical review.
Gas analysis
Select a target absorption band, detector range and blocking requirement.
Temperature measurement
Match the passband to the measurement range, sensor and operating environment.
FTIR spectroscopy
Define spectral range, substrate, angle and instrument geometry.
Imaging & sensing
Balance transmission, out-of-band rejection, AOI and physical format.
Thin-film coating inquiry
Bring the substrate. Define the response.
Discuss infrared anti-reflection coatings and other optical coating requirements from your sample, substrate or drawing.
Explore coating servicesTechnical inquiry
Send your filter requirements for review.
Include the application, wavelength target, bandwidth, blocking range, size, substrate and expected environment where available.
