Optical solutions for medical sector & biotechnology | Knight Optical (2025)

A globally renowned supplier of a comprehensive range of optical components to the medical and biotechnology sectors, Knight Optical is also a respected name in bespoke engineered optics solutions for a variety of surgical, diagnostic, imaging and detection and analysis applications, including:

Optical Expertise in Medical and Bioscience Applications

We have a considerable customer base across the sector and as a long-term partner with many spearheads within the field,
our optical components are regularly specified for large- and small-scale applications.

Laser Application and Intense Pulsed Light (IPL)

We understand the many challenges faced by medical laser instrument manufacturers and, at Knight Optical, it has always been our mission to help overcome them.

Our aim is to remove the barriers to creating precision, high powered instruments capable of delivering a tightly focused laser beam with minimum loss of transmission,
whilst avoiding overheating and damage, offering product longevity, complying with legislation and being able to withstand sterilisation and disinfection processes.

Whether your laser applications are for medical, cosmetic, biotechnology or research purposes,
you can rely on the globally renowned optical specialists at Knight Optical for the personalised support
and in-depth knowledge needed to resolve whatever may be holding you back from delivering precisely what your customers demand.

Optics for Detectors and Analysers

Some of the most vitally important devices used in the medical sector include detectors and analysers.
With a large proportion of these instruments utilising optical technology,
accuracy and reliability largely boil down to the precision quality of the optical components and assemblies that power them.

The evolution of optical engineering has had a significant impact upon all areas of the medical sector. From biomedical optics and spectrophotometric technology that have revolutionised sports medicine by allowing accurate blood oxygen and haemoglobin levels to be measured through the skin, to NIR spectroscopy used to monitor new born babies with critical health conditions, it is clear to see that this is an incredibly important area where the optics industry must work cohesively with medical equipment innovators.

Understanding Quality

We understand the importance of accuracy and reliability in systems for medical diagnostics and analysis. Our rigorous testing procedures –
using advanced metrology equipment and skilled QA inspectors – ensure all our products satisfy even the most specific requirements.
This applies to one-off custom parts and large production runs. Every single component we supply is proven to perform.
We will also provide you with all the information you require for your documentation. We can reassure you that there is transparency on your ordered items including a metrology report and a certificate of conformance to quality standards.
We are able to provide you with as much information as required to ensure that legal obligations are met, allowing your instrument to be approved for use as soon as possible.

Whether you want us to manufacture optical components based on your technical drawings, or need us to design parts or systems for your brief, we have the resources to make your concepts a reality. We always start by understanding your particular needs and expectations, and work to ISO 10110, BS 4301-1991, and MIL-PRF-13830B, to produce optical components and sub-assemblies at the correct quality, on time and within budget.

Knight Optical value every one of our customers, and therefore you will be assigned a dedicated account manager, who cares as much about your project as you do. They make the process of getting a quotation to receiving an order, as smooth as possible. We go above and beyond ensuring that your supply chain experience is as stress-free as possible.
