UV Optics

UV optics are a critical component of UV laser systems. They play a vital role in the transmission, shaping, and focusing of ultraviolet laser beams, which ultimately determine the precision, efficiency, and overall performance of the laser system. Wavelength Opto-Electronic designs and manufactures a wide range of UV optics, including UV F-theta scan lenses, UV beam expanders, and UV laser line mirrors for various UV laser applications.

F-Theta Lens – Optical Glass (SL)

The optical glass f-theta lens is an essential component in galvanometer scanning systems, widely used for laser marking, engraving, and cutting. It excels in delivering a focused spot to multiple points within the scanning field. Additionally, we offer lens adapters compatible with leading scan head providers globally.

Telecentric F-Theta Lens – Optical Glass (TSL)

Telecentric F-Theta lenses are a special type of lens system whereby the deflected off-axial laser beam can be perpendicularly focused on the workpiece as similar to the on-axial focusing beam. The advantage of the telecentric scan lens is that it can flatten the field curvature to the least distortion and yet offer superb spot quality throughout the scan field.

Achromatic F-Theta Lens (SLA)

Ronar-Smith® achromatic F-Theta lens is designed to limit spherical and chromatic aberration, and bring in two different wavelengths (working and visible wavelength) onto the same plane. This enables the transmission of wavelength-specific laser beam during laser-material processes while ensuring that the visible (feedback) and laser beam wavelength are temporally and spatially matched. Our achromatic scan lens enables machine vision in industrial processes for automation control and feedback while ensuring the product quality is not compromised.

Achromatic Telecentric F-Theta Lens (TSLA)

When a vision system is being integrated into a laser machining system, our achromatic telecentric f-theta lens is color-corrected between working wavelength and vision wavelength. The achromatic telecentric f-theta lens offers the benefits as same as the normal telecentric lens yet able to provide accurate vision positioning function. It is very useful for online inspection systems where the operator does not need to have an offline inspection on the workpiece.

UV Beam Expanders

Fixed Beam Expander (BEX)

Beam expander in laser system development is utilized for calibrating various elements. The diameter of the laser beam at the laser system output is adapted to the required diameter at the input of the objective lens. The beam expander is also primarily used in laser-material processes. Fixed beam expanders are also designed for specific beam expansion applications such as laser engraving. They also feature anti-reflection coatings and high transmissivity to maximize the efficiency of the beam expansion and reduce losses. The disadvantage lies in the fixed magnification factor and applications that require tuning of the output beam size are unable to perform.

Magnification: 1x – 50x
Beam Divergence: Adjustable
Design Type: Galilean
Pointing Stability: < 1 mrad

Manual Zoom Beam Expander (BXZ)

Zoom Beam Expander accounts for the short-fall of fixed beam expander by allowing the user to tune manually to the required magnification factor, depending on various processes that is required. These beam expanders are also designed for high power applications where magnification adjustments may be required. The concept of zoom beam expander works on the internal translation stages and focusing mechanisms to adjust and account for the changes in magnification continuously. It also takes laser divergence into consideration and performs relative adjustments without affecting the overall housing length.

Magnification: Continuous Zoom
Beam Divergence: Adjustable
Pointing Stability: <1 mrad
Operational Type: Manual

Motorized Zoom Beam Expander (BXZ-MOT)

Motorized Zoom Beam Expander accounts for the short-fall of fixed beam expander by allowing the user to tune automatically to the required magnification factor, depending on various processes that is required. These beam expanders are also designed for high power applications where magnification adjustments may be required. The concept of zoom beam expander works on the internal translation stages and focusing mechanisms to adjust and account for the changes in magnification continuously. It also takes laser divergence into consideration and performs relative adjustments without affecting the overall housing length.

Adjustment Speed: per magnification 5 sec
Baud Rate: 9600 bit/sec
Power Input: 9V
Interface: RS232 and USB
Pointing Stability: <1 mrad

UV Laser Line Mirrors

Laser line mirrors are designed with reflectivity R > 99.5% for Nd YAG laser applications. The laser line mirrors are available with us at fundamental line 1064nm with their harmonics 532nm, 355nm, and 266nm for 45° angle of incidence. These mirrors have a higher damage threshold, high optical quality, and are suitable for beam-guiding applications. Any different wavelength laser lines and different angles of incidence are provided upon request.

Dimension Tolerance: +0.0/-0.25mm
Thickness Tolerance: ±0.25mm
Surface Quality: 10/5 S-D
Clear Aperture: >90%
Reflectance: >99% at 45°
Angle of Incidence: 0-45°
Flatness: < λ/10 @ 632.8nm
Group Delay Dispersion: < 30fs² (for s & p-polarized light)
Coating: HR @ 350-400nm
Damage Threshold @ 20ns, 20Hz: 10 J/cm² for 355nm
