Description of Production:
Illumination receiving optical system: d/8 (diffuse illumination received in 8° direction), SCI (including added specular reflection) / SCE (without specular reflection), time measurement (no mechanical conversion) (based on DIN5033 Tei7, JIS Z 8722 condition c, ISO7724/1, CIE No. 15, ASTM E1164).

Integrating sphere size: φ52mm. Photon: two pairs of 40-mer silicon photodiode arrays
Spectroscopic means: plane diffraction grating. Measuring wavelength range: 360nm ~ 740nm
Measurement wavelength interval: 10 nm. Half width: about 10nm
Reflectance measurement range: 0 to 175%, indicating decomposition energy: 0.01%
Light source for measurement: pulsed xenon arc lamp × 3 (CM-2500d, xenon arc lamp × 2)
Measurement time: approximately 1.5 seconds (approximately 2 seconds for fluorescence measurement)
Minimum measurable interval: 3 seconds for SCI/SCE measurement (fluorescence measurement is 4 seconds)
Measurable times: 1000 times at 10 second intervals (when alkaline batteries are used) (SCI/SCE can be evaluated simultaneously for each measurement)
Measuring diameter / illumination caliber: MAV: φ8mm / φ11mm, AV: φ3mm / φ6mm (can be converted between the two) (CM-2500d only MAV) Repeat: standard deviation within 0.1% (but the standard deviation of the wavelength range of 360 ~ 380nm Within 0.2%)
Instrument error: ΔE*ad 0.2 or less (MAV/SCI) (based on the main body, the average value of the BCRA Series II 12-color measurement),
UV control: instantaneous adjustment (no mechanical adjustment) * with UV400nm conversion filter (no UV control function on CM-2500)
Measurement mode: stand-alone measurement / average measurement (automatic mode 3, 5, 8 times / manual mode)
Interface: RS-232C as standard
