Collimating Lens Assembly for Raytools BM06K Laser Head 120BT0300Z
A collimating lens in a laser cutter is an optical element that converts divergent light into parallel light. The collimator is equivalent to a convex mirror, and its main function is to convert the divergent light coming out of the optical fibre into parallel light, ensuring that the beam remains parallel during the cutting process, thereby improving the cutting accuracy and efficiency.
The working principle and application scenarios of collimating lenses.
A collimating mirror converts a divergent beam of light into a parallel or quasi-parallel beam through its convex reflection or transmission principle. In the laser cutting industry, collimators are often used in laser cutting heads, especially for early low-power cutting heads (e.g., 500 watts, 1000 watts) usually use 75 mm collimators, and high-power cutting heads (such as 3000 watts, 6000 watts) use 100 mm collimators.
Parameters and application scenarios for different types of collimating lenses.
The parameters of the collimating lens include diameter, focal length, etc. Common collimator diameters are 75 mm and 100 mm, and focal lengths are chosen depending on the application, e.g. 75 mm collimators are often used for low-power cutting heads, while 100 mm collimators are suitable for high-power cutting heads. In addition, collimators can be designed as monolithic, multi-laminated, or aspherical, with aspheric surfaces working best.
The difference and connection between collimating lenses and other optical components.
A collimating mirror is similar to a focusing mirror but works differently. Focusing mirrors focus light beams to one point to produce a high energy density focal point for processing, while collimating mirrors convert divergent light into parallel light to ensure that the beam remains parallel during transmission.
