Bandpass Interference Filter 50mm Square 810nm 12nm

VPF-50S-12-65-81000

Skip to the beginning of the images gallery

VPF band pass filter with effective diameter at 45mm square. Fit for experimentation that needs large collimated light incident on sample or on a large diverges light which requires a larger size band pass filter.

Details

◦The filters are made of dielectric multilayer coating and metallic coating which assure a steep rise and a sharp cut-off spectrum.
◦A selection of filter from the spectrum half-width from 10nm to 12nm, the center spectrum from 400nm to 900nm with 10nm increments.
◦The whole lateral side of the filter is painted in black to avoid scattered light effects.

Guide	For filter size of diameter 25mm, please see VPF-25C or see the high transmittance filter interference filter (YIF). WEB Reference Catalog Code/W3119, WEB Reference Catalog Code/W3118 For custom sizes or form which are not mentioned on-line or in this catalog or for any specific holder for this filter, please contact our Sales Division. Please refer to here for "Wavelength Characteristic Data (Reference Data, Transmittance: T[%]) " for each wavelength. For the models that are not in the form, please contact our Sales Division.
Remark	-
Attention	Heatproof temperature at 80°C (Celsius) as maximum, please avoid using it with higher temperature light-source. The filters are heat absorptive, therefore they are not fit to use with high power laser and high energy pulsed laser. The filters characteristic depends on the angle of incident. If the angle of the light axis inclines, the center wavelength shifts to shorter wavelength side and the transmittance may decrease. More 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 filters usage temperature of environment is set at 23℃ (Celsius), more the temperature is high more the center wavelength shifts to the longer wavelength side. Therefore a high precision set up is required for obtaining an efficient experiment each filter thickness is different.
