Large-Sized Aluminum-Coated Prism

The large-size aluminum-coated prism mirror features a K9 optical glass substrate with dimensions of 14×34×100mm. All seven surfaces are polished to a 60/40 scratch-dig surface quality, with four surfaces coated with aluminum film for the 400–700nm wavelength range. Its elongated prism design enables precise 90° optical path bending or beam translation in compact optical systems, reducing alignment complexity and enhancing overall system stability. The K9 material offers excellent optical transmittance and mechanical durability, making it suitable for a wide range of instruments and devices.

Practical Applications & Problem-Solving:

Optical Path Folding & Space Optimization – In space-constrained systems such as projectors, laser equipment, and optical inspection instruments, the prism reflects light at a 90° angle, effectively reducing the overall system footprint.

Large-Beam Reflection – With a 100mm length, the mirror accommodates large-diameter beams, making it ideal for optical systems that require wide-beam handling.

High Image Quality Assurance – Multi-surface polishing combined with 60/40 scratch-dig quality minimizes stray light, ensuring clear imaging in applications such as microscopes, digital cameras, and optical analyzers.

Stable Broadband Reflection – The aluminum coating delivers a reflectance of over 90% across the 400–700nm visible spectrum, meeting the reflection requirements of most visible-light optical systems.
