Bandpass Interference Filter 25mm Round 577nm 10nm

VPF-25C-10-50-57700

Skip to the beginning of the images gallery

VPF can transmit a specified wavelength range at a spectrum width (half-width) as precise as 1nm to 40nm. It is used to select spectral line from light-sources range from discharge lamp to different lasers wavelength.

Details

◦The filters are made of dielectric coating and metallic coating which assure a steep rise and a sharp cut-off spectrum.
◦The filters are metallically framed which make it easy to be mounted into a holder.
◦Large choice of spectrum, range from UV 214nm to IR 1550nm.

Guide	For filter size of 50 mm, please see VPF-50S or see the high transmittance filter interference filter (YIF). WEB Reference Catalog Code/W3121, WEB Reference Catalog Code/W3118 For custom sizes or center wavelengths or specified spectrum halfwidth which are not mentioned on-line or in this catalog, please contact our Sales Division.
Remark	-
Attention	The filters characteristic depends on the angle of incident. If the angle of the light axis inclines, the center wavelength switches to shorter wavelength side and the transmittance may decrease. The selected spectrum width is precise more the inclination tolerance is small. Make sure that the incident angle is set at 0 degrees for an efficient experiment. The filter usage temperature of environment is set at 23℃ (Celsius), increased temperature moves the center wavelength longer wavelength side. Therefore a high precision set up is required for obtaining an efficient experiment each filter thickness is different. Interference filters are heat absorptive, therefore they are not fit to use with high power laser and high energy pulsed laser.
