Compact, low-priced spectroradiometers that can instantaneously measure the irradiance spectrum of both pulse-type and continuous solar simulators. Equipped with functions to judge spectral matching based on various solar cell standards.

Main features

Developed specifically for measurements of solar simulators and natural sunlight

Spectral sensitivity characteristics are optimized for the irradiance wavelengths emitted by solar simulators and natural sunlight with improved S/N performance in the ultraviolet and near-infrared regions.

Wide measurement wavelength range

Provides spectral measurements from 300 to 1100nm, covering the wavelength range of silicon, dye-sensitized, and organic thin-film solar cells

Measurement of pulse-type solar simulators

A photodiode mounted on the reflective diffusion plate detects the light and sends a timing signal to the spectroradiometer to trigger the start of measurement, enabling measurements synchronized with the pulse light of solar simulators. Settings of delay time and trigger detection input levels are adjustable.
(Trigger capability included on S-2441 / 2442; optional accessory for S-2440)

High-speed repetitive measurements

Spectral variations in pulsed light can be continually traced with repeated measurements at 1-msec intervals. (S-2442 only)
