Observing the Wavelengths of Deep Ultraviolet (DUV) Lasers
- Accelerating the development of 266 nm wavelength conversion lasers
- Measuring excimer lasers (193 nm) and sterilization light sources (222 nm)
Speeding up Laser Optical Adjustments and Inspections
- Speeding up adjustment times for external cavity lasers
- Speeding up measurements of semiconductor lasers (LD) and surface-emitting lasers (VCSEL)
- Accommodating 100 % inspections of laser wavelengths for sensors (LiDAR) intended for self-driving systems
Features
- Instantaneous Spectrometric Measurements, Simultaneous Multi-Wavelength Measurements, and Real-Time Measurements
Using an array sensor, this instrument obtains an optical spectrum instantaneously, provides visualization of laser mode hopping and thermal and current characteristics, and speeds up measurement times.
- Heightens Wavelength Resolution with Multimode Fibers (MMF)
This instrument utilizes multimode fibers*1 to achieve a wavelength resolution of approximately 0.02 nm (Typ.), enabling the assessment of changes in fine peaks simply by orienting the optical fibers toward the measurement target*2.
- Wide Measurement Range Covering Ultraviolet (UV), Visible (VIS), and Near-Infrared (NIR) Light
Wavelengths from 185 to 1095 nm can be accommodated with a single unit, enabling measurements of everything from the 266 nm fundamental wave of deep ultraviolet lasers to wavelengths after wavelength conversion*3.
