Abstract

The invention discloses a transmissometer. The transmissometer comprises a light source, a condensing reflection device arranged in back of the light source and a signal acquisition device arranged in front of the light source, wherein a condensing device is arranged between the signal acquisition device and the light source. According to the technical scheme, a low-cost halogen lamp is used as the light source, so that the problem of over-high price of a xenon lamp can be solved. The halogen lamp serving as the light source affects the signal-to-noise ratio of the transmissometer, and in order to solve the problem of the signal-to-noise ratio, the transmissometer in the technical scheme comprises the condensing device. The condensing device can condense light emitted by the halogen lamp in a transmitted sample, so as to effectively solve the problem of over low signal-to-noise ratio of the transmissometer when the halogen lamp is used as the light source.

Description

technical field [0001] The invention relates to an optical detection device, in particular to a transmissometer with a higher signal-to-noise ratio. Background technique [0002] Signal-to-Noise Ratio (SNR) is an important performance index of a transmissometer. Generally speaking, the larger the signal-to-noise ratio, the smaller the noise mixed in the signal. On the contrary, when the signal-to-noise ratio is low, the noise is serious when the small signal is input, which may make it impossible to distinguish the value of the noise and the output signal, thereby greatly reducing the test performance. the accuracy. The existing transilluminator light source is generally a halogen light source, and its luminous intensity in the range of 400nm to 500nm is much lower than its intensity in the wavelength range above 500nm, which makes the signal-to-noise ratio in the range of 400nm to 500nm low, resulting in this The reliability of the test results in the wavelength range is ...
