Custom Size BK7 Optical Filter

Product description

This bandpass filter is designed for applications requiring precise wavelength selection, particularly in fluorescence microscopy and machine vision. With a center wavelength of 540 nm and a high transmittance of over 90% from 390 to 520 nm, it effectively isolates specific spectral bands while blocking unwanted wavelengths (OD4 from 550 to 780 nm). Its compatibility with BK7 substrate ensures durability and reliability in various environments.

Key Features

Center wavelength at 540 nm for optimal spectral fit in fluorescence applications.
High transmittance of >90% from 390 to 520 nm enhances signal detection.
OD4 blocking from 550 to 780 nm minimizes background interference.
Available in multiple sizes (D8, D10, D12, etc.) for versatile applications.
Minimum order quantity of 1 piece supports prototyping and small batch needs.
