ZWO IR-blocking filter D25

ZWO IR-blocking filter D25: sharpness and sensor protection for refractors

This interference filter blocks infrared light and protects the sensor of your ZWO ASI camera from dust and moisture. With refractors, it prevents the focus of visible and infrared light from diverging, which without a filter results in soft star edges and color fringing. The result: sharp images with pure colors.

For reflecting telescopes, the ZWO Clear Filter D25 suffices as a cover; mirrors do not have IR focus shift.

Features

• 90% transmission in the visible spectrum
• Blocks infrared and prevents focus differences
• Protects the sensor from dust, moisture, and scratches
• Multicoating minimaliseert verlies en halo’s rond sterren

Compatibility

Geschikt voor ZWO ASI-camera’s met D25-venster en M42-aansluiting. Monteer als eerste element op de camera of in het filterwiel; combineer met smalband- of kleurfilters voor extra contrast.
