Optical Systems Division of Jenoptik with new Technologies and Products at Photonics West 2014.
Silverline F-Theta Lenses with Broadband Anti-Reflection Coating for High-Power NIR-Diode-Laser-Applications
Jenoptik has added to its successful Silverline F-Theta product line new broadband F-Theta lenses with less absorption for high power diode laser applications. These lenses are covering a wavelength range of 900 to 1100 nanometers with high transmission performance. The specially developed anti-reflection coating is optimized for high transmission for the designated wavelength range. In addition, minimal absorption in the optics is key to high performance lenses for high-power laser applications. These lens properties ensure constant process parameters for the entire scanning fields and are particularly advantageous for applications with high-performance diode lasers running as high as the kilowatt range.
The first two versions of F-Theta broadband lenses are available for applications operating with focal lenghts of 160 and 255 millimeters together with a minimum spot diameter of down to 22 micrometers for single mode condition. Scanning fields with diagonals up to 160 millimeters can be processed. Application results from customers show very high performance with minimal thermal focal shift.
The lenses are advantageous for galvanometer scanner-based processes, such as those applied in mechanical engineering and car manufacturing, to process metals, sheet metal, and composite fibre materials.
New lens mount design for DUV optics
Jenoptik presents its newly developed thermally compensated lens mount design.
This patent pending technology is adhesive-free and especially designed for High-Numerical-Aperture (HNA)-DUV-optics. It reduces stress induced birefringence and improves the stability of optical components even under challenging environmental conditions.
In addition Jenoptik uses an innovative compensator concept to further exploit the outstanding opportunities of the new lens mount technology. It allows active manipulation with an accuracy of 10 Nanometers in a range of 300 Micrometers in x- and y-axis, even less if driven with state of the art actuators. The compensator ensures high-precision adjustment and position control for optical components in DUV Systems with high numerical aperture. Typical applications are optical beam delivery and illumination systems designed for micro-processing applications in the Semiconductor Equipment and Flat Panel Display industry.
The lens mount design is adaptable to optical materials like Calcium Fluoride or Fused Silica and can be made of stainless steel, aluminum and bronze. With many years of experience working with leading companies in the semiconductor industry, Jenoptik is a recognized partner from development through to series production of customized optical systems and high precision components.
New Point Source LED for UV and IR Spectral Range
Jenoptik has expanded its opto-electronics portfolio to include new customer-specific LED point sources for ultraviolet and infrared spectral range applications. In doing so, the company is adding to its red-emitting point source product group. These new LED point sources have an excellent homogeneous beam emissions area without side radiation and speckle formation. They ensure an evenly illuminated, sharply defined reflection on the radiating surface. The emissions area, shape, and optics of Jenoptik LED point sources can be fully customized and are therefore also suitable for integration into devices with space restrictions. Since they consume little power, the point sources are also ideal for use in mobile, battery-powered devices.
Tailored to meet the requirements of the application, the point sources can be assembled either as a chip solution, COB solution (Chip on Board), or a standard solution in the robust TO housing. Customer-specific COB solutions allow individual point geometries.
The new UV point sources for the wavelength of 360 nanometers are available with a spot diameter of 60 or 100 micrometers in the TO housing. They offer a well collimated radiation with an angle of radiation of up to seven degrees and a high power density focus. UV point sources are used predominantly in medical devices, for instance for blood analysis and fluorescence microscopy.
For applications in the infrared wavelength range Jenoptik offers new IR point sources group for a wavelength of 850 nanometers. These can be adapted to the customer's specific application with a spot diameter of 25 to 150 micrometers. The IR point sources make the smallest focus areas possible for high resolution in optical rotary encoders, as well ensuring efficient coupling to fiber optics for data transfer and a good collimation with high radiances for light barriers and motion sensors.
Jenoptik develops and manufactures customer-specific opto-electronic semiconductor devices that have high-intensity dynamics and are reliable and durable. High-quality LED chips, COB solutions, and a TO housing with an excellent processing capability allow for efficient system integration.
The technology for the new semiconductor devices was developed by Jenoptik and its partners as part of the WideBaSe research project investigating AlGaN-based UV technologies.
