Fluorescence filter is a key component widely used in biomedical and life science instruments . It's main function is to isolate and select the excitation band and emission band.
A typical fluorescence system has three basic filters : an exciter , an emitter and a dichroic mirror .
The characteristics of fluorescence filters are deep cutoff , small auto-fluorescence , and good surface quality , which are beneficial to fluorescence imaging . Therefore,it
is better to use single piece transparent glass as a substrate and two surfaces coating . However , most of single piece coating filters are high cost due to high difficulty in production .
Optolong provides high-brightness and high-contrast fluorescence filter sets , coating on single piece transparent glass .
Characteristics of Optolong fluorescence filters :
· Hard coating , double sided coating
· High transmittance , high-brightness
· OD＞5 blocking , high-contrast , no crosstalk
· Wavelength stability without shifting
