- The RL127 is characterized as a Large High Dispersion Bright Field ring light.
- Non-lensed LEDs disperse light at broad angles, providing “soft” lighting for applications that require short to medium working distances.
- The low-profile design is only .75” (19mm) thick, with an O.D. of 4.6” (117mm) and I.D. of 2.61” (66.3mm) allowing it to be used in space constrained applications.
- The I.D. provides a standard 67mm diameter thread with a pitch of .75mm for further mounting flexibility.
- A wide variety of wavelengths are available from UV to IR. An optional polarizer and/or diffuser may be used to further condition the light output.
- The RL121 delivers 20kLux at a working distance of 100mm.
- The RL3940 is characterized as a Folded Beam Dark Field ring light.
- Precisely aimed LEDs, along with an aluminum beam folder, provide a specific and repeatable light pattern on the imaging plane.
- The light provides up to 11kLux at a working distance of .6” (15mm).
- The RL3940 is available in a wide range of wavelengths from UV to IR.
- The folded-beam configuration provides dark field illumination in a compact 3.9” (100mm) housing.
- The housing’s large inner diameter can accommodate lenses up to 55mm in diameter.
- The light can also be ordered with an optional mounting ring.
Cryogenic Temperatures
- Fully isolated experiment space for true 4K temperatures during probing
- Cryogenic positioners to provide large travel ranges without warming up the device
- Integrated helium pot for high temperature stability of the device under test
- Fully dry cryogen-free cooler eliminates the need for expensive helium circulation systems
- Rapid cool liquid nitrogen option for faster cool down times
