Unmounted OD 4.0 Bandpass Filters
• Center Wavelengths from 365 to 1550nm
• 10, 25, or 50nm Full-Width Half Maximum Options
• High Transmission and Deep Blocking
TECHSPEC® Unmounted OD 4.0 Bandpass Filters are available with a 10, 25, or 50nm full-width half maximum
(FWHM). The narrowband 10nm bandpass filters are ideal for laser line separation, flame photometry,
or chemical detection applications. The broadband 25 and 50nm filters are used in a variety of life science and
machine vision applications, including preventing photobleaching of fluorophores and improving the signal to
noise ratio of imaging systems. TECHSPEC® Unmounted OD 4.0 Bandpass Filters are designed with center
wavelengths from 365 to 1550nm, covering common laser lines and spectral lines, and provide OD 4.0 blocking
outside of their passband. Standard diameter sizes of 12.5 and 25mm facilitate integration into benchtop
optical systems or life science instrumentation.
