• AstroSolar® Safety Film 5.0 for solar observation and photography at high magnification, telescope quality, Optical Density (OD) = 5.0
• Safe for visual solar observation (with additional optics) and imaging
• This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
• AstroSolar Safety Film is best suited for precision work with all astronomical telescopes and binoculars – just as well as for all photographic camera- and tele-lenses
• For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.

• AstroSolar® ECO-size Safety Film 5.0 for solar observation and photography at high magnification
• Size: ca. 140 x 155 mm, incl. DIY-instructions and DIY cutting-template – telescope quality – Optical Density (OD) = 5.0
• Safe for visual solar observation (with additional optics) and imaging
• This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
• For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.
• The film is from the same material as our proven AstroSolar® Safety Filme 5.0 in A4-size, due to high demand now availble in a smaller size at an economical price, suitable as solar filter for small telescopes, finders, binoculars, spotting scopes and camera lenses

• True 5MP sensor to capture and save high-resolution images and videos of your specimens
• 5-Element IR cut high-quality glass lens ensures sharper images
• 20x to 200x powers, great for low-power observation of 3D specimens (Note: Final magnification determined by monitor size)
• Professional, adjustable height stand included for hands-free operation
• 4 foot USB 2.0 cable for easy maneuverability when viewing large surfaces
• Intuitive software with measuring features
• Windows and Mac compatible 

The IMX533 is a 1-inch, 9MP CMOS image sensor in a square format with a 3.76 um pixel size, capable of producing frames at 20 frames/sec in 14bit mode.
Read out noise is as low as 1.0e which makes it comparable to SCMOS or EMCCD sensors and highly suitable for high definition, low noise imaging.
