ZWO IR pass filter 1.25" for infrared photography

ZWO IR pass filter 1.25" for infrared photography


The ZWO 852 nm IR pass filter is made for infrared-sensitive cameras such as the ASI224MC and enables spectacular recordings.
♦ IR Pass Filter - Interference filter with 1.25" filter thread

♦ Blocks all visible light, the filter only opens just before 800 nm (picture left)

♦ The filter allows exciting shots, such as the veins through the palm of your hand (pictured left - through the ASI224MC camera, IR pass filter and lens)

♦ The filter is interesting for lunar, planetary and solar photography.



ZWO 1.25" 850nm IR pass filter for infrared photography
The IR pass filter is suitable for cameras that are sensitive to infrared light. Cameras with a built-in IR cut filter cannot be operated with this filter. Cameras with infrared sensitivity are for example ASI224MC or ASI185MC. But DSLR cameras, where the infrared protection filter has been completely removed, and CCD cameras are also suitable for infrared photography.

Functionality and possibilities:
The IR pass filter blocks all visible light. The normal detection range is up to around 700 nm, which is deep red light. The transmission curve of the ZWO filter only rises steeply just before 800 nm and reaches the maximum transmission at 860 nm.

This extreme filtering enables exciting areas of application, such as:

♦ Long-distance underground photography - Haze becomes more transparent due to reduced scattering, as does the skin on the hand shot
♦ Planetary photography - hiding the short-wave range has a calming effect on the seeing. Venus and Mars shots in particular are spectacular.
♦ Experiments with deep sky photography - with suitable telescopes
