Collimated laser diodes are an assembly of a laser diode with a specified collimating lens within a small package. Slow axis collimation can be done with an additional lens. Note that different dispersion equations apply to different lens diameters and numerical apertures. For most laser diodes, the beam divergence is so substantial that it is advantageous to use aspheric lenses for beam collimation in order to avoid significant spherical aberrations of the collimated beam. ELECTRON provide customized solutions diode laser modules to fit your requirements. The cylindrical shape of the lens allows it to be easily aligned and mounted. We have over 1600 different lenses in stock at our New York facility. We offer both glass and plastic aspheric designs to fill most typical application requirements. In either case, most laser diodes require a collimating lens with a large numerical aperture (NA) to efficiently capture the widely By adjusting the distance between the laser diode and the collimating lens, one can collimate the laser diode output. We have over 1600 different lenses in stock at our New York facility. Laser diode beams typically have a slow axis and a fast axis (see Figure 2). The cylindrical shape of the lens allows it to be easily aligned and mounted. Although the value of this parameter must be determined through indirect measurement techniques, it is a characterization of the lens’ optical performance.

The fast-axis collimating lens shown in blue reduces the divergence of the laser diode beam to a value close to zero. A range of visible, infrared and green diode laser module consisting of laser diode, electrical driver and collimating lens in an black anodized or copper housing. The collimating beam dimensions are given by the equations BD⊥ = 2 × f × sin(θ⊥/2) BD|| = 2 × f × sin(θ||/2). The fast axis is called the fast axis because the divergence is larger along the fast axis than the slow axis. The dependence of √A and N0, on wavelength is described by the dispersion equations listed at the end of this product guide. There are different collimators that are available: Some broad-area emitters are sold with a fast axis collimation lens (FAC lens) fixed to the output facet.

Molded Glass Aspheric Laser Collimator, Glass Laser Collimating Lens We use the molded glass aspheric lens process creating the laser collimating lenses from diameter 2~15mm for the laser diode collimation and collimated beam applications. Lenses should be handled with plastic tweezers, preferably those with a tapered end. Aspheric lens is being used to collimate a laser diode beam. It consists of a laser diode holder, a collimating lens holder, and a high numerical aperture (NA) collimating lens, with a focal length f. The lens is housed in a threaded receptacle that is screwed into the collimating lens holder. Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. For diode stacks, one often uses an array of cylindrical micro lenses, each one working for one of the contained bars. This entails the use of a desiccant (e.g., silica gel) or a heat source to prevent humidity from leaching the lens material.

In a SELFOC lens, rays follow sinusoidal paths until reaching the back surface of the lens. The above equation relates the pitch (P) to the mechanical length of the lens (Z) and the gradient constant. Great Versatility for Use With Most Laser Diodes Our aspheric lenses are diffraction-limited molded glass lenses with typical wavefront quality better than λ/20 rms. √A Index gradient constant (mm-1) Because the properties of emission from various types of laser diodes can be quite different, different types of laser diode collimators have been developed. The paraxial (first-order) behavior of these materials is modeled by assuming sinusoidal ray paths within the lens and by allowing the quadratic term in Equation 1 to vanish in the ray-tracing calculations. Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode. This collimate the output only in that direction, so that it is no more necessary to mount additional optical parts very close to the diode. Cleaning Collimators for single-emitter laser diodes: Single-emitter laser diodes usually exhibit substantially different divergence in two orthogonal directions. SELFOC® Collimating Lenses are designed to be compatible with CD lasers and other types of packages.

The lens is housed in a threaded receptacle that is screwed into the collimating lens holder. Shipping costs. Either the major axis is compressed or the minor axis is expanded to make a circular beam. At times it is necessary to clean the lens surfaces due to the presence of some dust or film which may impair the image. High-power laser diodes are often equipped with collimators only for the fast direction. We offer lens assemblies and elements that are available in standard combinations of focal lengths, wavelength, and barrel styles. Nous proposons des milliers de produits dans toutes les catégories de vente, afin de satisfaire toutes vos envies. There are several applications in which a laser diode collimator can be used, some of which are: The dimensions of the collimated beam are determined by two factors – the far field divergence angles θ⊥ and θ||, of the laser diode being used, and the focal length of the collimating lens. The lens can be glued or … Storage Handling To achieve the best performance, the numerical aperture of the lens should be significantly larger than that of the laser diode – for example: by a factor of two. In addition to humidity requirement, the lenses need to have sufficient spacing to avoid potential damage such as chipping and scratching from other lenses. We accept payments with Apple Pay, Google Pay, VISA, MasterCard, American Express and Discover. All of the usual paraxial quantities may be calculated with the help of the ray-trace matrices given at the end of this product guide. The Pick-Up Lens is mounted in an anodized aluminum holder.

For short term storage (less than a month), the plastic box and foam packing in which the lenses are shipped will provide adequate storage. The CAW100 is a plastic lens of 785 nm with a numerical aperture of 0.195. In the world of optics, web searches are no substitute for our direct, comprehensive, customer-tailored application assistance. Aspheric lenses do not introduce spherical aberration and are therefore are commonly chosen when the collimated laser beam is to be between one and five millimeters. In typical cases, one has about 10° divergence (full width at half maximum) in the “slow” direction and ≈30° in the “fast” direction. Our experienced design team will offer custom laser diode collimators with desired divergence and beam size and shape. However, many applications exist where a single lens is used to either focus or collimate the beam. The figure below illustrates different ray trajectories for lenses of various pitch. laser lens Laser Focal Lens, Collimation Lens, laser collimating lens, laser diode collimating lens, laser collimating lenses, laser collimation lens, laser focal lens, laser diode focal lens Laserland have focal lens which is coated for certain wavelength. The CAW100 is a plastic lens of 785 nm with a numerical aperture of 0.195. The most simple and popular way to collimate a laser diode beam is by using a single aspheric lens. The distance between the laser diode output facet and the collimation lens needs to be identical to the focal length of the lens, because otherwise the beam after the … Using Aspheric Lenses: Part II – Choosing the Right Lens for Diode Collimation One of the most common uses for aspheric lenses is in the collimation of edge emitting diode lasers. A light ray that has traversed one pitch has traversed one cycle of the sinusoidal wave that characterizes that lens. Cavities of single-mode laser diodes are in the range of hundreds of microns. θ– Maximum angle from object below axis Selmux™ Wavelength Division Multiplexers, Furukawa signs an agreement to distribute Go!Foton products in Latin America.
