Types of LED Light Source

Types of LED light source

Annular light source: directly irradiate above the measured object.

Strip light source: there are three kinds of irradiation effects: direct, oblique and metering.

Linear light source: it has condensing effect, and high brightness can shorten the exposure time of the camera.

Hollow square light source: the angle can be adjusted to match the object to be measured with different characteristics and working distance.

Backlight light source: irradiate from the back of the object to be tested.

External coaxial reflective light source: the light can be irradiated on the object to be measured in parallel by the lateral light source through the spectroscope.

Internal coaxial point light source: it needs to be used with coaxial lens.

Hemispherical ridge cover light source: the light source can diffuse into a uniform irradiation area through the diffusion cover.
