  1. Next generation high performance instrument for measuring Luminance and Chromaticity of light sources.

  2. A complete range of instruments Accuracy CS-1000A/S/T Spectroradiometer CS-200 Chroma Meter with spectral engine CS-100A Three filter type of Chroma Meter Price

  3. CS-200 - Main features Wide measuring range: 0.01 to 20,000,000 cd/m² High accuracy: Spectral fitting method assures close matching to CIEsensitivity curves Portability: CompactLightweightBattery powered Optional accessories:Close up lenses ND filter Calibration plates for object mode Angle Finder Soft case 3 Measuring angles: 1° , 0.2° , 0.1° Small area measurement (0.1mm) Wide application range:Research & Development Quality assurance PC software: Standard accessory Professional version optional Various functions: Synchronized Measurements Selectable measurement speed USB connection to PC Large LCD display Data storage

  4. CS-200 - High accuracy due to spectral sensor Spectral sensitivity of the CS-200’s 40 sensors Composite Z sensitivity created by calculation Composite X sensitivity created by calculation Composite Y sensitivity created by calculation

  5. CS-200 - Spectral fitting method Peak wavelength : 435 nm Peak wavelength : 430 nm • CS-200 utilizes a photo diode array with 40 sensors • Output data is corrected by adding coefficients for each sensor and wavelength position

  6. CS-200 - Spectral fitting method ＋ ＝ ＋ ＝ Target function Compensation factors Sensor 1 = 0 Sensor 2 = 0 Sensor 3 = 0 Compensation factors Sensor 1 = 0.7 Sensor 2 = 0 Sensor 3 = 1.3 Compensation factors Sensor 1 = 0.4 Sensor 2 = 0 Sensor 3 = 1.6 Composite sensitivity

  7. CS-200 – CIE colour matching functions • Spectral fitting method provides precise matching to the sensitivity of human eye and results with superior inter instrument agreement. • CS-200 specification: • f1 = 1% (Class L is 2%)

  8. Spectral sensitivity • Why is matching to CIE Vλ curve (f1) that important? • Photometric value is specified by the area of radiant energy which is covered by the Vλ curve. • Ex. Illuminant A • All the red area • Ex. LCD • Green area

  14. CS-200 – Colour management network • Absolute accuracy and superior inter instrument agreement allow building of colour management networks without using physical reference objects or user calibration

  15. CS-200 - Wide measuring range & excellent repeatability • Low luminance like 0.01 cd/m² can be measured • Ex.: Contrast measurements • High luminance up to 200,000 cd/m² can be measured • With 0.1° aperture up to 20,000,000cd/m² • Optional ND filters expand the range (1/10 & 1/100) • Ex.: Projector lamps, high pressure lamps, … • Repeatability (Standard light source A) • 0.01-1 cd/m² Lv ±0.03 cd/m² ±1digit --- (2 s / SLOW) • 1-2 cd/m² Lv ±2 % ±1digit xy 0.008 (2 s / SLOW) • 2-4 cd/m² Lv ±2 % ±1digit xy 0.004 (2 s / SLOW) • 4-8 cd/m² Lv ±2 % ±1digit xy 0.002 (2 s / SLOW) • 8-200,000 cd/m² Lv ±0.2 % ±1digit xy 0.001 (2 s / SLOW)

  16. CS-200 – Relation of repeatability and measurement speed Measurement time: Actual time required for measurement (integrating time ×2+shutter open/close time + calculation time) Integrating time: Time sensor is measuring light (exposure time) Auto mode switching levels: FAST -> SLOW: Below 20 cd/m² SLOW -> FAST: 40 cd/m² or above

  17. CS-200 - Selectable measuring angle • Three build in apertures provide measuring angle of 1°, 0.2° and 0.1° • Quickly selectable by slider switch on instrument • Small area like  0.1 mm can be measured • CS-200 • Measuring area of  0.5 mm • Optional close up lens No.122 • Measuring area of  0.3 mm • Optional close up lens No.107 • Measuring area of  0.1 mm

  18. CS-200 - Selectable measuring angle 0.2° aperture Small size • LED parts • Instrument panel • Switch panel 0.1° aperture Very small size or distant • Pixel of LCD or PDP… • Brake lamp • Signal lights 1° aperture Middle & large size • LCD, PDP, EL display • Light source like lamp or back light

  19. CS-200 – Synchronized measurements Emission period The emission period can be set by inputting the numerical frequency value (40.00 to 200.00Hz)(The measuring period is an integral multiple of the emission period (for periods longer than 300ms) Measuring period

  20. CS-200 – Object colour measurements • With the optional white calibration plate CS-200 can be used for object colour measurement • Selectable 2˚ and 10˚ Standard Observers

  21. CS-200 – Eyepiece adjustment

  22. CS-200 – Large display with backlight

  23. CS-200 – Colour space display • Colour space • Lv x y • Lv u’ v’ • Lv T ⊿uv • X Y Z • Dominant wavelength
