Calibrated light source unit
L7810-03
The L7810-03 is a calibrated lamp light source that delivers extremely high levels of "stability" and "reproducibility". It is available in a convenient set including a xenon lamp, lamp housing and power supply to allow easy operation and stable light output with high reproducibility. It emits light over a wide spectral distribution from 200 nm to 800 nm and is supplied with a calibration certificate with a JCSS (Japan Calibration Service System) logo mark.
Applications
- Light level control of light source
- Sensitivity control of optical sensor
- Light intensity measurement and studies of photoreactions
(Light resistance, light curing, etc.) - Quality control of photometric equipment
(Medical analysis equipment, semiconductor inspection systems, imaging devices, etc)
Light intensity drift (Typ.)
Spectral irradiance

Notes
*1: Spectral irradiance is measured at a point 50 cm away from the reference plane of the lamp housing.
*2: This is a general guide for recalibration to maintain calibration reliability. Please contact our sales office for recalibration fee.
*3: This is the total amount of time that the lamp can be recalibrated to serve as a calibrated light source.
