This ensures that any external ambient light is blocked and only the laser line wavelength is passed.
Laser line bandpass filters are ideal for transmitting laser light while suppressing ambient light as well as lower intensity secondary laser lines.
Different standard full width half maximum values in bandpass filters e g 1 1 2 4 3 8 or 11 are specified.
Our premium bandpass filters are hard coated for higher transmission and are more durable and longer lasting than our standard bandpass filters.
The laser line bandpass filter is placed in the optical path between the laser and the sample.
Bandpass filters with extremely narrow passbands.
Narrow bandwidth 1 3 nm and excellent blocking from 300 to 1200 nm.
Bandpass filters dichroic beamsplitters edge and notch filters raman spectroscopy filters mirrors and fluorescence filters sets.
To achieve the best results use filters with bandwidths as narrow as 1 2nm and optical densities of od 6 0.
The center wavelength shifts linearly with temperature less than 0 02 nm c.
Our laser line bandpass filters cover most of the common laser lines and feature excellent out of band blocking of less than 0 01 10 4.
Home spectroscopic filters bandpass filters laser line laser line iridian s laser line filters are amongst the best in the world featuring high transmittance greater than 90 in the pass band.
Each specification refers.
The highly reflective side of the filter should generally face the source minimizing the thermal load on the blocking glass and epoxies.
The customer is free to choose the central wavelength in bandpass filters as well as the cut on and cut off wavelength in broadband bandpass filters.
Thorlabs selection of dielectric coated spectral filters are presented here.
The highly reflective side of the filter should generally face the source minimizing the thermal load on the blocking.
The bandpass and laser line filters shown on this page feature center wavelengths of 700 nm to 1650 nm.
It is important to pay attention to the tolerance.
