With Firecrest Ultra we have taken this process one step further and we now "lap and polish" the filters, a process previously only carried out on our cinema grade filters. So as well as the superb neutrality and durability that Firecrest deliver, the filters now benefit from enhanced clarity and sharpness and are the most optically flat photographic ND filters in the world, regardless of focal length.

Experience the Marvel of a Solar Eclipse Like Never Before! Witness the breathtaking spectacle of a solar eclipse through the unparalleled clarity of Formatt Hitech's cutting-edge filters. Our exclusive collection of Full Spectrum Infrared Neutral Density Filters is meticulously crafted to let you capture the eclipse in its full glory. Each filter is a masterpiece, handcrafted in the UK with the utmost precision, using only the finest materials available. Designed specifically for the unique demands of solar eclipse photography, these high-density glass filters ensure the highest fidelity in color and detail. With Formatt Hitech, you're not just taking a photograph; you're preserving a once-in-a-lifetime celestial event with unmatched optical performance. Embrace the ultimate in clarity and detail, and make your solar eclipse experience truly unforgettable.Density 16-24 Stops. Do not use lighter ND to look at the sun.

What is an objective lensused for

Leica apochromats are objectives for applications with highest specifications in the visual range and beyond, offering field flatness up to 25 mm. The absolute values of the focus differences for the red wavelength and the blue wavelength to green wavelength (3 colors) are ≤ 1.0 x depth of field of the objective.

The objective lens of a microscope forms a magnified, real, intermediate image of the sample or specimen which is then magnified further by the eyepieces or oculars and observed by the user as a virtual image. When a camera is used to observe the sample, then a phototube lens is installed after the objective in addition to, or even in place of, the eyepieces. The phototube lens forms a real image of the sample onto the camera sensor. The objective’s numerical aperture (NA), its ability to gather light, largely determines the microscope’s resolution or resolving power to distinguish fine details of the sample. Also, the working distance, the distance between the sample and objective, and the depth of field, the depth of the space in the field of view within which the sample can be moved without noticeable loss of image sharpness, both greatly depend on the properties of the objective lens.
