Optimal optic surface flatness

To measure the optic surface flatness, industrial interferometers of the Fizeau type are used - IT-200, IT-100.The collimated wavefront reflected from the reference surface of the reference plate and the tested surface of the part forms an interference pattern. A CMR-1 mercury lamp (the wavelength of the green line of mercury is 0.546 μm) is used as a light source. The interference pattern is viewed through the telescope, which consists of an objective lens, a lens, and an eyepiece with a reticle.With the help of a switchable mirror, the interference pattern localized on the reference surface of the reference plate can be recorded onto photographic film using a camera. The subject table can be moved in three directions. The tilt of the stage is possible in the horizontal plane around two mutually perpendicular axes. Optical lenses use only the most optimal parameters to achieve maximum wavelength and strength to ensure the longest possible lifespan.

UV polarizer

UV polarizer is an indispensable accessory that any more or less literate amateur photographer should have. The purpose of such a product is to remove reflections from surfaces (except for metal). In bright sun, it can "reduce" the brightness of the sky, make it a little more textured (in fact, the filter simply does not allow reflection from small water droplets in the air to form). And if you need to film a body of water, PF can help hide unwanted reflections from the surface of the water, making it appear more transparent (for example, when shooting a lake from the shore).Do not forget, however, that it takes a part of the light flux (up to 2 exposure steps, it depends on the quality of the product). But there is a way out - using exposure compensation if you apply a polarizing filter. If the lighting is frankly so-so, you need a tripod. Besides, such a filter can improve the colors in the picture - mind you, without using Photoshop or any other similar program. The explanation for this is the same - the filter cuts off some light waves and converts them into polarizing others, thereby preventing reflections, which should be understood as any reflection, and not at all specular glare.
