Bandpass Interference filter / VPF-50S-10-90-80000A
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. The new product has a higher transmittance.

| Guide | ▶For filter size of diameter 25mm, please see (VPF-25C) or see the high transmittance filter interference filter(YIF). ▶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. |
| 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. |
