Day and Night Lens

The night mode mechanism of the Day & Night camera, which is becoming a big trend in the market, uses the infrared zone area (700nm -1000nm) So when a standard Day time only lens is installed outdoors the image blurs and needs to be refocused for night mode use.

By adopting a specialized optical glass and utilizing the high designing technical skills we have developed and realized an extremely low longitudinal chromatic aberration lens making possible a round-the clock surveillance without any refocusing from visible light range (Day mode/Color image) to near infrared light range (Night mode/Black and white image).

When a camera which serves day and night is used with a lens exclusively for Day light(Visible rays), it accepts visible rays in the daytime and near infrared rays at night.

The two kinds of rays with different wavelengths form an image in focus at a different focal point, and produce out-of-focus images unless it is adjusted in the evening or at dawn.
