Lenses

Rod lenses are precision optical components designed for a variety of applications, including fiber coupling and laser diode beam shaping. These lenses are cylindrical in shape and are made from high-quality optical glass, ensuring minimal light loss and distortion. Applications of Optical Glass Lenses Fiber Coupling: Zero Working Distance: Rod lenses with a 0 mm working distance are ideal for collimating single and multi-mode optical fibers. The ability to position and glue the lens directly to the emission source ensures optimal alignment and efficient light transmission. Collimation: These lenses are particularly effective for collimating light emitted from optical fibers, ensuring that the light travels in a straight path with minimal divergence.

An optical bandpass filter is used to isolate a band of wavelengths from the total spectrum by providing a band of high transmission and bands of high rejection of spectral energy on both the long and short wavelength sides of the transmission band. Features High selectivity: The 940nm bandpass filter can accurately select and transmit light with a wavelength of 940 nanometers, while effectively blocking light of other wavelengths to ensure the purity of the optical signal. Low insertion loss: Advanced coating technology and material selection make the filter extremely transmittance in the target band, reducing the loss of optical signals during transmission. Excellent environmental stability: The use of high-quality substrates and stable coating processes ensures the stable performance of the product under extreme temperature and humidity conditions and extends its service life. Compact and light: The design is compact, light, and easy to integrate into various optical systems to meet the application requirements of different scenarios. 1.

Central wavelength: Each narrow bandpass filter has a specific central wavelength, which is the wavelength position of the maximum transmittance it is designed to pass.

Optical mirror is an optical element which has reflective function. Accordingly shape, it can divide into three parts, that is flat mirror, spherical mirror, aspheric mirror. Accordingly, degree of reflection, it can divide into two parts, that is total reflection mirror and half reflecting mirror. On the back of the optical glass make a metallic silver or aluminum or gold film by vacuum coating to reflect the incident light. First surface mirror the reflected image has no distortion, no glint, and it’s also called front surface mirror, it’s widely used for optical high-fidelity scanning reflection imaging, beam bending, interferometry, imaging and illumination. Commonly use polishing glasses or metal as substrate made a reflected coating on it, including metal film and dielectric coating, metal coating material including gold, silver, aluminum, aluminum mirror has very high reflection rate from UV to IR, film fastness and stable, silver mirror have high reflectance ratio from VIS and IR, AOI changed slightly and low polarization effect, gold mirror has very high reflectance rate, strength and stability in IR area, better than silver coating. Metal film is soft and easily to scratch and damage, so it’s often plated with a protective film outside the metal film, if need high reflection ratio choose dielectric coating film, it can improve the reflectivity and reduce the absorption loss. AOI and wavelength will affect the reflectance ratio, commonly AOI is 0° or 45° CCRQ supply flat surface mirror, spherical concave mirror, cylindrical mirror, elliptical mirror, right angle prism mirror, Hot mirror, cold mirror, Flat mirror etc, many of stock size for choosing, select a coating appropriate to your application or contact us with your need wavelength and wavelength range, more choosing as following, more details please contact us directly.

Optical prism is an optical element which accordingly incident light and outgoing light to make turning ray of light. In the optical path, the prism can making the light offset and changing the direction of the image and also has the function of changing the angle of outgoing and incident light, such as deflection 90° or 180°.Prim widely used on laser research, laser optical systems, optical image, machine vision and other fields and products. Right Angle prism also called Right Angle Bending Prism, because it can turn light 90° by internal reflection of hypotenuse, or turn light 180° through two right angle prism surfaces, accordinlgy customers demand. Many different coatings applied to these prisms, some common types are Anti- reflection coating on two legs, Aluminum protected coated on hypotenuse by black sealing paint to ensure grazing incidence reflection and two angle surface make VIS AR or NIR AR, accordingly customers demand. These prims are suitable for optical delay lines and for high power use.
