CA13752_STRADA-SQ-FT Application Field and Working Principle

Optics - lenses have found the broad application in various walks of life, from photography to astronomy. CA13752_STRADA-SQ-FT, a kind of refractor lens by Chroma Technology Corporation (CTC), is no exception and has already been widely used in many area including precision measurement, detection system and so on.

CA13752_STRADA-SQ-FT Structure

CA13752_STRADA-SQ-FT is a high-precision uncoated achromatic doublets with strong focusing ability, which consists of two separate optical components (connected with a spacer) made of crowns and flints. It provides light with different wavelength focusing in the same focal plane. Specifically, it is comprised of a spherical crown element (made of crown glass) and an achromatic doublet whose both lenses are formed from different glasses, containing a negative Meniscus lens and a positive Bi-convex lens.

CA13752_STRADA-SQ-FT Application Field

Thanks to the superior light transmission capability and low dispersion, CA13752_STRADA-SQ-FT lens are used in many sensitive measuring systems such as high-resolution imaging, optical Doppler velocimetry, scanning microscopy and digital holographic microscopy.

Compared with other refraction lenses, CA13752_STRADA-SQ-FT has the additional advantages, such as wider range of aperture size, small thickness, better durable performance. Therefore, CA13752_STRADA-SQ-FT lenses have found even wide applications in observation astronomy and advanced therapies. For example, in astronomy, CA13752_STRADA-SQ-FT are used to capture the stars in the night sky with clearest and most detailed images. In phototherapy, CA13752_STRADA-SQ-FT are also used due to its stability even when facing very low aperture or high power light.

CA13752_STRADA-SQ-FT Working Principle

Like other lenses, light transmits through CA13752_STRADA-SQ-FT is because the optical properties contained in it. The whole lens is made up of two optical components, a positive bi-convex lens and a negative Meniscus lens. A bi-convex lens is made of two curves like the outer glasses of eyeglass, while a Meniscus lens has curved surfaces with one side is concave while the other is convex.

When light hits the lens, it will pass through the first optical component and be refracted when it touches the curved surface of this lens. After that, light will moved to the second optical component, where it will hit one curved surface first, of which the radius is changing in an opposite way compared to the radius of the previous curvature surface. As a result, the refracted light will get back on the normal line of its original path and be collected in the focal plane. Finally, a clear and sharply focused image is formed.

Conclusion

CA13752_STRADA-SQ-FT lens created by Chroma Technology Corporation (CTC) has become a significant part in modern optical systems. Thanks to its very strong focusing ability, it is widely used in precision measurement, detection systems and even astronomy and therapies. Its superior light propagation and low dispersion not only remarkably improve the imaging performance, but also give it a lot more application areas.
