Optolong UV/IR Cut Filter
Optolong UV/IR Cut Filter
Safety Warning: NEVER USE THIS FILTER FOR OBSERVING THE SUN. Directly looking at the sun through this filter can result in irreversible eye damage or blindness.
- Designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image
The Optolong UV/IR Cut Filter serves a specific purpose in the realm of photography and videography, designed to block ultraviolet (UV) and infrared (IR) wavelengths that fall outside the visible spectrum. This filter is particularly valuable for improving image sharpness when used with digital cameras and video equipment that lack built-in IR protection filters for their image sensors or have undergone modifications.
Key Uses and Benefits:
- Compatibility: The Optolong UV/IR Cut Filter is compatible with a range of devices, including color CMOS and CCD cameras, as well as DSLRs that have been modified for specialized purposes.
- Astrophotography: It finds a special application in astrophotography when paired with monochrome CCD cameras, enhancing the quality of astronomical images.
- Focusing Aid: Additionally, this filter can assist photographers and videographers in achieving better focus, contributing to sharper and more precise images.
- Dust Shield: It also serves as an effective dust shield, safeguarding the lens against the accumulation of dust duringlong-exposure photography sessions.
Advanced Coating Technology:
The Optolong filter boasts advanced coating technologies to ensure its longevity and optical excellence:
- Multi-layer Anti-Reflection Coating: This coating reduces reflections and boosts light transmission through the filter.
- Non-Cementing Optical Substrate Coating: It is applied to the optical substrate to enhance resistance against scratches.
- The filter utilizes Ion-Assisted Deposition Coating Technology for precise and stable performance. This technology guarantees that the filter's central wavelength (CWL) remains consistent even in the face of temperature fluctuations.
- During the coating process, a planetary rotation system is employed to ensure uniform and accurate coatings, resulting in high transmission in the pass-band and superior optical density in the off-band.
In summary, the Optolong UV/IR Cut Filter is a valuable accessory for photographers and videographers, aimed at enhancing image quality by selectively blocking UV and IR wavelengths. However, strict adherence to safety warnings is crucial, especially when it comes to avoiding solar observations to prevent potential eye damage.
