Abstract
The utility model relates to a low infrared response silicon photocell photometry detecting device, comprising a casing whose inner part is provided with a cosine corrector, a colour filter, silicon photocells and a fixing pressing ring in sequence. Any position between the cosine corrector and the silicon photocells is provided with insulating glass, and the photic creamy white ceramics is used in the material of the cosine corrector. The insulating glass is added in the utility model to prevent infrared ray, and the infrared response of the detecting device is reduced. The cosine corrector made of the photic creamy white ceramics can make the favorable homogeneity, stability and diffusing property realized and ensured, and the cosine correction is easy to realize.
Description
The utility model relates to detector, relates in particular to low infrared response silicon photocell photometric detector.
In modern photometry is measured, in order to replace visual measurement; The subjective error of getting rid of human eye to improve measuring accuracy and sensitivity, has extensively adopted photo-detector.To the metering of each physical quantity of photometry, most critical be the correction of human eye vision function V (λ) of the spectrum sensitivity response curve of detector, the height of revising level is closely related with the measuring accuracy of instrument.
Because silicon photocell has good long term stability and serviceable life, in photometry test, replaced selenium cell to obtain using widely, but the spectrum sensitivity response curve of silicon photocell and CI E1931 standard human eye vision function V (λ) than big difference.Generally all adopt the color filter of particular design that curve is revised in the world, the height of correction level directly influences the measuring accuracy of instrument.
Silicon photocell photometric detector of the prior art is by the cosine corrector, and color filter that coloured glass is formed and silicon photocell are formed, and the infrared response of detector is bigger, brings than mistake in the measurement of luminosity.
The purpose of this utility model provides a kind of low infrared response silicon photocell detector.
The utility model is taked following measures in order to achieve the above object: low infrared response silicon photocell photometric detector comprises housing, is provided with cosine corrector, color filter, silicon photocell, fixing trim ring in housing successively.Arbitrary position is provided with heat-protecting glass between cosine corrector and the silicon photocell.
The utility model has compared with prior art increased heat-protecting glass to stop infrared ray, has reduced the infrared response of detector; Good homogeneous, stability and diffuse properties can be realized and guarantee to cosine corrector with the milky white ceramic making of printing opacity, is easy to realize that cosine proofreaies and correct, and the milky white pottery of printing opacity has good material consistance, is convenient to processing.
Elaborate below in conjunction with accompanying drawing:
Low infrared response silicon photocell photometric detector comprises housing 6, is provided with cosine corrector 1, color filter 3, silicon photocell 4, fixing trim ring 5 in housing successively, and arbitrary position is provided with heat-protecting glass 2 between cosine corrector and the silicon photocell.Color filter is composed multi-disc coloured glass and is tieed up, and the material that the arbitrary position between multi-disc coloured glass is provided with heat-protecting glass cosine corrector is the milky white pottery of printing opacity.
Claims (3)
1. one kind low infrared response silicon photocell photometric detector, it comprises housing (6), in housing, be provided with cosine corrector (1), color filter (3), silicon photocell (4), fixing trim ring (5) successively, it is characterized in that arbitrary position is provided with heat-protecting glass (2) between said cosine corrector and the silicon photocell.
2. a kind of low infrared response silicon photocell photometric detector according to claim 1 is characterized in that said color filter is made up of multi-disc coloured glass, and the arbitrary position between multi-disc coloured glass is provided with heat-protecting glass.
3. a kind of low infrared response silicon photocell photometric detector according to claim 1 and 2, the material that it is characterized in that said cosine corrector are the milky white potteries of printing opacity.
