Knight Optical has successfully launched a range of Stock Optical Domes for Submersible ROVs underwater imaging, sensing and exploration applications, where protection of electronic sensor systems from harsh liquid and gas environments is essential.
A dome is essentially a window that has two parallel curves faces. Our domes ensure high clarity and transmission in the UV-NIR and FarIR spectrums allowing for accurate measurement.
Knight Optical is a trusted, established and reliable supplier to manufacturers of underwater ROVs for surface and deep water exploration. With our excellent record delivering quality, metrology tested optical domes & windows; we like to think we are your best solution for custom ROV dome and window solutions. Our products are used by satisfied customers in the ROV industry worldwide. Contact our experts and find out why!

We can supply you with a custom made Diamond turned aspheric lenses for use within Thermal Imaging Cameras.
Thermal Imaging Cameras work similarly to traditional visible camera systems; while traditional cameras form images using visible light; thermal cameras form images using infrared radiation; operating in wavelengths as long as 14µm.
Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays, potentially replacing a multi-lens system. This in turn provides the camera system with a better image quality.
Knight Optical offers diamond turned aspherics from a range of infrared materials including Germanium (Ge), Calcium Fluoride (CaF₂), Zinc Sulphide (ZnS), Zinc Selenide (ZnSe), Aluminium (Al) and chalcogenide glasses like AMTIR (Ge33As12Se55 )

KO can offer Metallic Neutral Density Filters for use in Photographic Applications.
We supply a range of Metallic Neutral Density (ND) Filters for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specifications. What’s more, our Metallic ND Filters are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications.
Our Metallic ND Filters reflect (with a metallic coating) light neutrally over a wavelength range (typically visual). They can be used to lower the intensity of light prior to the image plane.
These are often used in photography, allowing photographers more flexibility with their setups to achieve desired effects. Often, an ND filter will be used in conjunction with a long exposure to prevent washed-out and overexposed images. They can also be used to add motion blur, reduce depth of field and to use a wider aperture.

Our precision grade N-BK7 windows are often used to seal optical enclosures & act as a protective window for the optical and electrical component behind the window, particularly within CCTV and ANPR systems where there is a risk of damage. N-BK7 provides excellent transmission in the visible and near infrared spectrum which can be enhanced still with our Anti Reflective coatings.
Our stock range of ¼ wave N-BK7 or equivalent windows are supplied either uncoated or with the option of an Anti-Reflective coating on both faces with extended BBAR for visible and NIR applications within the 450-900nm wavelength range. We can also offer custom solutions for your application, whether it is a custom size or a coating to optimise a different wavelength range, beamsplitter coated or mirror coated to meet your bespoke requirements.
