LE007 reflective surface light source - reflective light source for simulating different ambient light in a standard optical imaging laboratory

In response to the needs of camera testing in the mobile phone, automotive imaging, security and medical imaging industries, Positron has introduced a range of specialised test equipment. These include: reflective surface light sources, ultra-high brightness wide dynamic test systems, ultra-wide angle camera brightness uniformity (Shading) test systems, and integrated camera resolution test systems for ultra-low light levels and ultra-wide angles, etc.

LE007 reflective surface light sources can be divided according to the different applications into.

· Vertical reflective surface light source（LE007-S）   ：To provide illumination primarily for reflective test cards.

· Hanging reflective surface light source（LE007-H）：Mainly for applications such as live lighting and light source rooms.

Divided into standard visible light, increased infra-red (IR) light and high brightness (HD) according to functional characteristics for meeting the different needs of users, the reflective surface light source is one of the essential pieces of equipment for standard image testing laboratories. The new version of the LE007 light source takes into account the adjustment of low light levels of 0.1lux and normal illumination, making it suitable for image testing needs in many industries.

Main applications of the LE007 series light sources.

· MTF	· Test dynamic range	· Infrared camera test
- Colour reproduction, AWB, SNR	· Test distortion	· Horizontal colour difference
