Laser Optical Lenses

1. BK7 Plano-Convex Lens

The BK7 plano-convex lenses are available in a variety of laser lines. We can offer laser anti-reflection coatings with different wavelengths including 405nm, 468nm, 532nm, 650nm, 808nm, 980nm, 1064nm, 1319nm, and 1550nm. Designed with high light transmission rate at the specified laser wavelength, our lens is ideally used in Ne-He or Nd:YAG laser systems. With a maximum reflectivity of less than 0.25% per surface at the design wavelength, it is able to achieve superior light transmission through integrating with multiple optical components. We can offer as many as thousands of ready-made radius of curvatures. Custom-design and –fabrication available upon request.

In the following tables, we will use the abbreviations: OD  means outside diameter, EFL means effective focal length, BFL means back focal length, R1 and R2 means radius, TC means center thickness, TE means edge thickness. All dimensions are in mm. In “Part Number”, XXXX means laser wavelength in nm.

2. Fused Silica Plano-Convex Lens

Our plano-convex lenses are made from UV-grade fused silica, giving outstanding thermal properties, exceptional purity, and excellent environmental durability. We offer anti-reflection coatings with different wavelengths such as 405nm, 468nm, 532nm, 650nm, 808nm, 980nm, 1064nm, 1319nm, 1550nm, and more. It is especially suitable the use in He-Ne, Diode, and Nd:YAG laser systems due to its design of maximum light transmission at the specified laser wavelength. Through combining multiple optical parts, our lens with a maximum reflectivity of less than 0.25% per surface will give superior light transmission. Like our other products, we can supply as many as thousands of ready-made radius of curvatures.

The common laser wavelengths include 266nm, 355nm, 405nm, 468nm, 532nm, 650nm, 808nm, 980nm, 1064nm, 1319nm, 1550nm, 10.6um and so forth. All laser coatings of optical windows, mirrors, and lenses make use of dielectric coatings for optimization of transmission and reflection performance at the designated laser wavelength, thus enhancing the damage threshold of laser. They are ideal for various kinds of laser systems. In addition, we also can supply the design of coating according to the requirements of our customers.

When you order a lens from above lists, please define a laser wavelength (XXXX in the part number) according to your applications. Also please refer to the following descriptions and click the hyperlinks for more information on transmissions/reflectance at the given laser wavelengths.

STS Series Multi-element Lenses

Multi-element lens systems minimize the imaging errors of single lenses and provide precision focusing for non-scanning applications. You have to distinguish between monochromatic and achromatic systems.

Monochromatic systems are only corrected for a specific wavelength. So they are most suitable for laser applications. Especially fused silica lenses in air-spaced design are preferably chosen for collimation or focusing of high power laser.

We offer mounted air spaced multi element systems in fused silica and optical glass.

Achromatic systems have to consist of lenses with different glass types and dispersions. Only a matched combination allows the correction of the chromatic error especially in the visible range. Usually components are cemented. That leads to a reduced damage threshold of the achromatic system, which limits the use of laser with average powers of less than 200 watt.

Aspheres

Aspheres offer the great advantage to accomplish imaging tasks with one optical element where lens systems were needed otherwise. Main advantages of aspheres are:

The combination of high purity fused silica and low absorption coatings decreases the thermal induced shift of focal length and working distance.

Another application of an asphere is beam shaping with respect to the intensity distribution or the phase. A typical conversion is the change of a Gaussian profile into a top-hat profile. For material processing, this form has the advantage of a more homogeneous removal of surface material, steeper borders between removal zone and surrounding material and a resulting smaller heat affected zone (HAZ).

Our capability allows production of aspheres up to diameter 200 mm. Measurement setup (interferometric wavefront test, tactile and optical 3D profi lometry) enables us to ensure a surface quality of 0.15 μm PV(fWD) and RMSi < 0.025 μm depending on geometry. Even sagittal heights z(r) up to 21 mm are measurable enabling the production and test of very steep radii at certain diameters.

Our range of products covers unmounted and mounted precision aspheres out of fused silica with focal lengths from 20 mm to 400 mm, which are usable for focusing and collimation. Special forms and customized versions are available on request.  Our technological possibilites are listed below.
