HP880D Mini goniophotometer

Details:

HP880D mini goniophotometer

HP880D is employed to measure the photometry parameters of small LED lamp and single power LED. The instrument includes optic dark chamber and aperture, can be operated at optional distances without dark room environment supporting. The solution meets CIE127 and IEC61341 requirements.

 

Characteristics and specifications:

Range of luminosity: 0.1-30.000c d

Accuracy of luminosity: class 1

Spread angle of light beam: θ(50%)θ25%θ75%

Center intensity: 10

Angle range: -900-+900

Angle accuracy: ±0.20

Measuring angle interval: 10

Fine V(λ)corrected detector

Draw luminous intensity distribution curve and measure the spread angle for light beam automatically

Meet the requirements of GB&CIE

Options of the distance:1 m/3.16m

Max diameter of tested reflector lamps:15cm

The tested data meets the international and national standard requirements. IESNA file format output can be transfered by other illumination and luminaire dsign software .
