Uniform Light Collimating Lens LED Uniform Light Variable Zoom Optics

Uniform light collimating lens LED optical collimating lens Uniform light variable zoom optical collimating lens

Requirements Description：

Spot illumination uniformity reaches 90%

Can adjust to obtain light spots with different diameters ranging from 4mm to 12mm

Require the chip plane to be attached to the bottom of the lens barrel

Require to ensure that the chip installation positioning deviation is less than 0.03

1, What is the uniformity?

The uniform lens can adjust the diameter of the light spot and is characterized by good illumination uniformity, reaching 90%

2，Which lamp can this lens be paired with?

Universal chips, any type of chip can be used. If the user has a requirement for uniformity in the contrast value, this type of lens is very suitable

3，Is the light spot adjustable between 4mm-12mm?

Yes! Adjust the front group and then tighten it, so that the diameter of the light spot can be infinitely adjusted between 4 and 13

4，What is the focal length?

At a distance of 20mm, the spot diameter is 4mm; at a distance of 44mm, the spot diameter is 13mm. This effect is achieved by using the Japanese Nichia NCSU033C

5，What is the angle of light emission

The angle of light emission varies according to the size of the spot diameter Refer to the drawing for the range of angle changes.

6，What is the principle of this lens based on?

The principle of this lens is based on the principle of projectors used in conference rooms, so the uniformity of illumination values is good. The aperture designed is circular, so the light spot is also circular. If the aperture is changed to square or triangular, the resulting light spot will also be enlarged and reduced compared to the same period last year Shape.
