Reflective Mirror / 90 Degree Mirror for Laser Machines

Reflective Mirror, commonly known as a 90 Degree Mirror, is an important optical component used in laser machines to redirect the laser beam through the optical path. It is widely used in CO₂ laser cutting, engraving, marking, and industrial laser systems.

We supply high-quality Laser Reflective Mirrors / 90 Degree Mirrors in Bangladesh for industrial laser applications, available in different materials, dimensions, coatings, and wavelength specifications.

What is a 90 Degree Mirror?

A 90 Degree Mirror is designed to reflect the laser beam and change its direction, commonly by approximately 90 degrees within the laser optical system.

It helps maintain accurate beam alignment and efficient laser power transmission throughout the optical path.

Applications

Laser reflective mirrors are commonly used in:

• CO₂ Laser Cutting Machines

• CO₂ Laser Engraving Machines

• Laser Marking Machines

• Industrial Laser Systems

• CNC Laser Machines

• Laser Tube & Sheet Cutting Machines

• Laser Beam Delivery Systems

Common Mirror Materials

Depending on the laser wavelength and application, reflective mirrors may be manufactured using:

Molybdenum (Mo) – Suitable for demanding industrial laser applications and offers high durability.

Silicon (Si) – Commonly used in CO₂ laser systems and provides good thermal performance.

Copper (Cu) – Offers excellent thermal conductivity and is used in various high-power laser applications.

Other Optical Materials – Available according to specific laser system requirements.

CO₂ Laser Mirror

For CO₂ laser systems, reflective mirrors are typically designed for the 10.6 µm wavelength.

The correct mirror coating and substrate are important for maintaining high reflectivity and minimizing optical losses.

Common Sizes

Reflective mirrors are available in different sizes according to the laser machine and mirror mount.

Common sizes include:

• 20 mm

• 25 mm

• 27 mm

• 30 mm

• 38.1 mm

• 40 mm

• 50.8 mm

• Other custom dimensions

Exact diameter, thickness, coating, and curvature should be matched with the existing laser system.

Why Quality Reflective Mirrors Matter

A high-quality mirror helps provide:

• High laser beam reflectivity

• Low optical loss

• Stable beam transmission

• Accurate beam alignment

• Better cutting and engraving performance

• Reliable operation in industrial environments

A damaged, contaminated, or incorrectly specified mirror can reduce laser performance and affect cutting quality.

Signs of a Damaged Mirror

Inspect the mirror if you notice:

• Reduced laser power

• Poor cutting performance

• Unstable beam alignment

• Reduced engraving quality

• Visible stains or contamination

• Scratches or coating damage

• Burn marks or discoloration

• Excessive heating of the mirror

Regular inspection and proper cleaning are recommended for maintaining optical performance.
