CBCオプテックス List of Products and Services

This is a mirror that reflects specific wavelengths highly due to a dielectric multilayer film. By using appropriate processing conditions, mirrors with high energy resistance can be produced. Custom manufacturing of broadband reflective mirrors, dual-wavelength reflective mirrors, harmonic separators, and more is also possible.

CBC Optics Co., Ltd. is capable of multi-layer coating design, small lot prototyping, and mass production. 【Products (excerpt)】 ○ Anti-reflective coatings ○ Bandpass filters ○ Dichroic mirrors/filters ○ Laser mirrors For more details, please download the catalog or contact us.

Our company manufactures optical filters, mirrors, and splitters using dielectric multilayer films, and also adds functionality through anti-reflective coatings (AR coatings) and various metal films. Additionally, we accommodate coating on crystals as substrate materials. We accept orders for prototypes from small lots to mass production, with short delivery times. 【Features】 ■ Customizable transmission wavelength range and blocking range (bandpass filters) ■ Available in plate and cube types, with the plate type capable of AR coating (beam splitters) ■ Customizable for wide-area reflection and dual-wavelength reflection (laser mirrors) ■ High heat resistance and durability coatings possible through layer design (AR coatings) ■ Proven track record in film deposition of materials such as Al, Ag, Au, Be, Cr, In, Mo, Ni, Pt, and Inconel (metal films) 【New Product Information】 *New deposition machine introduced* We are now capable of producing narrow-band bandpass filters in the ultraviolet range, as well as high-difficulty coatings that require maintenance of surface accuracy after deposition. *For more details, please refer to the catalog. Feel free to contact us with any inquiries.*

At CBC Optics, we offer distinctive metal deposition film products, including "various aluminum mirrors," "various metal mirrors," and "ND filters." The "various aluminum mirrors" are mirrors that have a protective film applied to aluminum to protect the metal film from oxidation and scratches. The "various metal mirrors" include aluminum mirrors, gold mirrors, silver mirrors, and copper mirrors. The "ND filters" are filters that reduce the amount of light entering the lens. We apply coatings that suppress surface reflection by layering chromium oxide and overcoating dielectric films to minimize changes over time. 【Features】 [Various Aluminum Mirrors] - We can design the protective film to meet customer needs and provide the best reflectivity. [Various Metal Mirrors] - Ideal for measurement devices, laser equipment, medical applications, optical imaging, and automotive use. [ND Filters] - Allow for opening the aperture or reducing shutter speed during photography. For more details, please contact us or download the catalog.

We offer "Laser Mirrors (HR Coating)" and "Anti-Reflective Coatings (AR Coating)" as high-durability products for high-power lasers. Laser Mirror: A specially coated film optimized to achieve high reflectivity at specific laser wavelengths. Anti-Reflective Coating: A high-durability anti-reflective coating used in newly developed high-power laser devices. Laser Damage Threshold (LIDT) Measurement: Measuring the damage threshold by irradiating optical components with lasers. 【Features】 ■ Laser Mirror (HR Coating) High reflectivity of over 99.0% → Laser damage threshold of 122 J/cm² at a wavelength of 1064 nm → Laser damage threshold of 16.8 J/cm² at a wavelength of 355 nm ■ Anti-Reflective Coating (AR Coating) Ensures high durability → Laser damage threshold of 21.0 J/cm² at a wavelength of 532 nm ■ Advantages of Our Laser Damage Threshold (LIDT) Measurement 1: Ability to investigate damage thresholds, lifespan predictions, and defect densities 2: Capable of handling substrates from very small to large sizes 3: Possesses various types of lasers 【We will exhibit at OPIE'23 Laser EXPO】 April 19 (Wed) - 21 (Fri), 2023, 10:00 - 17:00 @ Pacifico Yokohama
