Frequently Asked Questions (FAQ)
What is a Visible Light Bandpass Filter?
A visible light bandpass filter is an optical device designed to transmit a specific range of visible wavelengths (typically between 380 nm and 780 nm) while blocking unwanted shorter and longer wavelengths.
What do the CWL and HPB specifications mean?
CWL stands for Center Wavelength, which is the peak transmission midpoint of the bandpass range. HPB stands for Half Peak Bandwidth (also known as FWHM - Full Width at Half Maximum), indicating the width of the spectral band at 50% of peak transmission.
What does the Cut-off Depth (e.g., OD4, OD6) represent?
Optical Density (OD) defines the blocking capability of the filter outside the transmission band. OD4 represents a blocking level of 10^-4 (0.01% transmission), while OD6 represents a blocking level of 10^-6 (0.0001% transmission), providing higher contrast and lower noise.
Can these filters be customized to specific sizes?
Yes, our standard optical filters support size customization. Standard dimensions range from Φ0.1 mm up to 300 mm to fit various system requirements and mounting configurations.
What are the typical applications for visible light bandpass filters?
These filters are widely utilized in machine vision inspection systems, fluorescence analysis (such as FAM, Rox, and Cy5 excitation/emission), biotechnology instrumentation, clinical diagnostics, and spectroscopic applications.
