  • Universal Lens Filter

    This Universal Lens Filter combo pack includes two 50mm filters and one 90mm filter, all meeting ISO 12312-2 safety standards for direct solar photography. The integrated Thousand Oaks Density-5 SolarLite film rejects 99.999% of incoming sunlight, allowing you to safely capture detailed images of sunspots and solar eclipses with your camera, binoculars, or small telescope.

    ISO 12312-2 Certified: 99.999% Solar Rejection

    The core of this filter is the renowned Thousand Oaks Density-5 SolarLite film, which is fully compliant with the ISO 12312-2:2015 standard for eye safety. This film blocks 99.999% of the Sun's energy, protecting your camera's sensor and your eyes from harmful radiation. Through the filter, the Sun appears in a crisp, natural orange tint, revealing the sharp edges of large sunspot groups against the photosphere.

    Universal Fit: 50mm and 90mm Filters for Multiple Optics

    Designed for maximum flexibility, each filter is constructed from double-layer heavy card stock that folds into a secure, cup-like shape. This allows it to fit over the front of various optics without needing specific filter threads. This pack includes two 50mm filters, perfect for a pair of binoculars or small camera lenses, and one 90mm filter for larger telephoto lenses, spotting scopes, or small refractors.

    • Foldable Design: Creates a friction-fit cell that securely covers the front aperture of your instrument.
    • Anti-Reflection Interior: The inside surface is black to absorb stray light and reduce internal reflections, ensuring a high-contrast solar image.
    • Lightweight Construction: The card stock material adds negligible weight to your setup, preventing balance issues on smaller mounts or tripods.

  • How do I attach the Universal Lens Filter to my camera?

    The filter is designed to be folded into a cup shape that fits snugly over the front of your camera lens, binocular objective, or telescope. You create a friction fit by gently pushing it over the barrel of your optic. Always ensure it is secure and cannot be accidentally dislodged while observing.

    Is this Universal Lens Filter safe for looking directly at the Sun?

    No, this filter is an accessory for cameras, telescopes, and binoculars only. It is not designed to be used as handheld eyewear or solar eclipse glasses. The film itself meets the ISO 12312-2 standard, making it safe for viewing through an optical instrument it is properly attached to.

    What color will the Sun appear through this Universal Lens Filter?

    The Thousand Oaks SolarLite film used in the Universal Lens Filter produces a pleasant and natural-looking crisp, clear orange tint. This is a popular color for visual observation and photography of the Sun's surface features.

    Can I use the two 50mm Universal Lens Filters on my 10x50 binoculars to view a solar eclipse?

    Yes, this is an ideal use case. The two 50mm filters are designed to fit over the objective lenses of most standard binoculars, including 10x50 models. This allows for safe, magnified, and comfortable stereo viewing of events like a total solar eclipse or large sunspot regions.

    Will the 90mm Universal Lens Filter fit my 80mm refractor telescope?

    Yes, the 90mm filter is sized to fit over the dew shield of many small telescopes, including common 80mm refractors. The foldable design provides some flexibility, but you should always measure the outside diameter of your telescope's dew shield to confirm a secure fit before pointing it at the Sun.

    Why is the inside of the Universal Lens Filter black?

    The interior of the filter is black to minimize internal reflections. A reflective inner surface could bounce light between the filter and your lens, reducing image contrast and potentially creating distracting glare. The black interior ensures the view remains as sharp and high-contrast as possible.
