Telecentric F-Theta Lenses

LINOS Photonics has extended the broad range of their F-Theta series by the addition of two telecentric F-Theta lenses. With these lenses, the laser beam is guided vertically over the entire scan field, enabling a high depth of focus for marking objects in laser material processing.
At a 100-mm focal length for wavelengths of 532 nm and 1064 nm, the scan field is 77 mm. Spot sizes are 7 μm and 13 μm, respectively, with an incoming beam bundle of 15 mm. Deviation of the telecentricity is
< 0.9%.

BBO and RTP Pockels cells for regenerative amplifiers and pulse pickers

The Pockels cells developed by Linos with BBO and RTP electrooptical crystals are designed for use in lasers that generate ultrashort pulses with high output power and fast repetition rates, among other applications. In conjunction with fast switching electronics, also available from Linos, these cells can pick individual pulses from pulse trains or control the number of round trips in regenerative amplifiers. The new Pockels cells from Linos feature a compact, rugged and dust-tight housing and little to no piezoelectric oscillation. The cells are available with a variety of apertures. The BBO versions can be supplied as double Pockels cell to reduce the switching voltage. Because of their excellent characteristics, ultra-short pulse lasers (fs lasers) constructed using these Linos cells are increasingly found in materials processing and medical technology applications.

LINOS expands its bm.x series
Advances in the NIR and UV range

The number of lasers that emit light in the NIR range is growing all the time. To facilitate research and development processes and provide dedicated support for these technologies in industrial applications, it is important to offer complete system solutions. This is the path LINOS is taking with the extension of their bm.x series: the latest model is specially designed for use with light sources in the NIR range of 725 nm to 1050 nm.

The modular beam expansion system from LINOS consists of a basic module and a set of interchangeable, focusable attachments, easy to insert and remove, that determine the expansion ratio. With this package, the expansion can be changed to 3x, to 4x, 5x, 8x or 10x quickly and easily.
LINOS has added to the existing 450-650nm/1064nm version five new systems specially designed for the NIR range to the bm.x series of modular beam expansion systems. This development opens up new areas of application for LINOS equipment. As in the existing bm.x series, the special optical design ensures minimal wave front distortion at wave lengths from
725 nm to 1050 nm. Specifically for this range, all optical components have an anti-reflective coating of R < 0.5%. The time-tested combination of coating and low-absorption materials ensures high damage thresholds, which is particularly important when using laser systems. For the UV range three new models with 1.5x, 2.0x, and 2.5x expansion have been added. These models make the quality of the bm.x series available for the wavelength range of 266-405 nm.

Features LINOS bm.x NIR and UV beam expanders:
? Reduction of beam divergence
? Anti-reflective coating for 725 to 1050nm and 266 to 405 nm
? Input lenses made of fused silica (all lenses for UV models)
? Compatible with LINOS modular system
? High-precision focusing
? Expansion ratios: 3x, 4x, 5x, 8x and 10x (NIR), 1.5x, 2x and 2.5x (UV)

Optical design software WinLens

LINOS is pleased to offer a new version of the WinLens Plus software suite. The graphics [lens drawing and performance graphs] have been significantly enhanced to allow for full zoom and pan. These graphs now create printouts using the full printer resolution and can even be saved as DXF files.
Another very useful addition is a Quick Focus tool. A single click will adjust the image plane distance to minimize OPD or TRA across all object points.
The WinLens suite has always been able to model LINOS lens specified purely by the relevant part code. WinLens can now use the new 9 digit part numbers and will recognize & apply the thin film coatings defined in the final 3 digits of the code. The latest LINOS lenses have been added to the database.
To compliment the component database update, we have revised the glass database and added the Chengdu glasses.

Rapid Ronar F-Theta Lenses

LINOS Photonics has extended their Rapid Ronar F-Theta series by the addition of two new lenses. In addition to the existing focal lengths of 63 mm, 100 mm and 160 mm, focal lengths of 254 mm are now available as well, for 1064-nm and 532-nm wavelengths. The Rapid Ronar series was developed for small, fast scan heads with apertures of 5 to 8 mm. Thanks to short mirror distances, a relatively large field can be scanned with much smaller lens diameters, which means lower costs.
The scan field is 157 mm with spot sizes of 31 μm and 62 μm, respectively, with an incoming beam bundle of 8 mm.
