RFQ Information
We are developing an NIR spectroscopy device and require visible bandpass filters to monitor the health of halogen lamp light sources. The filters must block all wavelengths outside the visible spectrum (400-3000 nm) to prevent optical errors at the detector.
Required specifications:
• Dimensions: 17.5±0.1 mm × 9.5±0.1 mm
• Thickness: 1 mm
• FWHM: 50±5 nm
• Center wavelength: ~550±10 nm
• Optical density: >3 across 400-3000 nm range
Order quantity: 20 pieces.
Please provide detailed specifications and pricing.
