The TLC (Thermal Lensing Compensation) patent US 8,274,743 B2 optic design passively compensates thermal lensing for high power collimators and focusing lenses. Through the use of special optical materials and optic design, thermal lensing for lasers with powers in excess of 1KW is reduced to less than the Rayleigh range of the lens design.

Figure 1 shows a simple fused silica best form singlet.

Figure 2 shows an overlay of the same lens that has a 230°C temperature gradient applied. The blue rays are light focused at ambient temperature and the green rays represent the focus at the elevated temperature.

Figure 3 shows the close up the Haas TLC Optics™ in figure 1 with the same focal length and temperature gradient.

TLC Optics™ balances dn/dT between two high-power laser optical materials, along with optimized thickness, air spacing, and curvatures, to minimize thermal lensing from 20°C to 250°C using a proprietary optical design merit function. This ensures your application stays in focus from start to finish.

• Supports lasers up to 20kW+.
• Available in 30mm and 50mm diameter optic sets.
• No thermal stabilization time required.
• Custom configurations available.

Unlike traditional thermal management methods, TLC Optics™ eliminates the need for several minutes of stabilization, ensuring consistent performance even under high thermal gradients that conventional systems can't handle.
