Goniophotometer

A goniophotometer is a photometer for measurement of the angular dependence of optical quantities. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and  luminance distribution of lamps and luminaires. The latter two are proposed in recent years as the development of light & lighting.

  • LED620 is designed for measuring the luminous intensity distribution, luminous intensity, spread angel of light beam and electrical characteristics of LEDs. The rotation around γ axis is automatically while the rotation around C axis is manually.

  • A traditional goniophotometer with rotating mirror (mirror on optical axis). The test light source can remain its prescribed burning attitude, but the stability of the test light source is not high as it moves in a large space during the measurement.
    It can achieve CIE A-α, CIE B-β, CIE C-γ solutions with diffe...

  • A traditional goniophotometer with rotating mirror (lamp on optical axis). It overcomes the problem of the stability of the tested light source. But there still some unsolvable problems.
    It can achieve CIE A-α, CIE B-β, CIE C-γ solutions with different software.
