Description

MidOpt PE530-25.5 Broad Bandwidth Photopic Response Bandpass Filter

When using the PE530 with a monochrome (black-and-white) camera or other sensors, together with a broadband light source (such as the sun), the resulting spectral response replicates in the same proportions what the human eye will see, closely matching the CIE 1931 photopic luminosity curve. This is highly useful in applications requiring accurate lux, lumen, or cd/m2 readings.

Photopic response filters are also used with ambient light detectors; for example, photoelectric sensors are used to control when infrared LED lighting is used in day-night imaging applications. They also automatically control display backlight brightness and ambient light sensors used in mobile phones to dim or brighten a device’s screen appropriately.
