ZWO Blocking Filters UV/IR 1.25″

ZWO Blocking Filters UV/IR 1.25″ - improve your color balance and sharpness

Many CCD and CMOS color cameras are sensitive to infrared (IR) and ultraviolet (UV) light. This causes distortions in color and sharpness - especially when using refractors and lens systems. The ZWO UV/IR blocking filter solves this immediately.

This filter allows only visible light to pass through and blocks the UV and IR areas that are outside the focusing range of lenses. Result: improved color balance and sharper stars without halos.

Applications:

• Ideal with color cameras without internal IR-cut filter (such as ZWO ASI294MC, ASI585MC, ASI533MC)
• Recommended for refractors and lenses that are not apochromatically corrected
• Safety filter in solar observation with solar film or Herschel prism

What you prevent or improve with it

✓ Faded or shifted colors when using color cameras
✓ Stars with halos or blurred edges
✓ Infrared pollution in refractors
✓ Additional UV protection for sun perception (in combination with sunscreen film)
