October 2026 Hot Products
Each month, we review the products that generated the most interest from customers across a range of industries. The best-selling products in October were Bandblocking Dichroic Filters, Planoconcave Lenses and Vacuum Pickup Systems. These products highlight the continued demand for components that support precision light control, beam manipulation and the safe handling of delicate optics.
Bandblocking Dichroic Filters
These optical filters, also known as notch filters, are designed to block a specific wavelength band while transmitting surrounding wavelengths, making them useful for applications where unwanted light must be removed without significantly affecting overall system performance.
Compared with traditional glass filters, dichroic bandblocking filters offer sharper transition regions between transmitted and blocked wavelengths, helping to improve blocking accuracy.
Their negligible absorption also makes them suitable for higher-power applications where thermal effects can be a concern.
Our stock range includes filters covering blocking regions across the 500-600 nm range, available in standard 12.5 mm and 25 mm diameters, as well as 50 mm square formats. Custom wavelengths and dimensions are also available.
Common applications include fluorescence systems, laser systems and Raman spectroscopy, with demand continuing across scientific, medical and laser-based industries.

Planoconcave Lenses
Featuring one plano surface and one concave surface, these lenses have a negative focal length and are commonly used to increase the divergence of converging beams. Their ability to reduce optical power within multi-element systems also makes them valuable for beam shaping and optical design.
One of the most common applications for planoconcave lenses is within laser beam expanders, where controlled beam divergence is required. They are also frequently incorporated into imaging systems, optical instrumentation and a wide variety of laboratory-based optical setups.
We stock N-BK7 plano-concave lenses in diameters from 6 mm to 25 mm and focal lengths ranging from 10 mm to 1000 mm. Custom options include alternative substrate materials, custom focal lengths and anti-reflection coatings.
Their versatility across scientific, machine vision and laser applications continue to make them a consistently popular component.
Vacuum Pickup Systems
These products provide a practical solution for handling delicate optical components safely and efficiently.
When working with precision optics, even minor contamination or accidental damage can affect performance. Vacuum pickup tools allow operators to handle lenses, filters and other optical components without direct contact, helping reduce the risk of fingerprints, scratches and handling damage.
Our range includes both handheld vacuum pens and desktop vacuum pickup systems. Handheld units are well suited to lightweight optics and small components, while powered desktop systems offer secure handling for a wider range of optical assemblies.
Supplied with multiple interchangeable tips, these systems support a variety of component sizes and handling requirements. They are widely used in optical assembly, inspection and cleanroom environments where maintaining component integrity is essential.
Whether selecting filters for spectroscopy systems, lenses for beam control or handling equipment for optical assembly, customers continue to rely on components that combine dependable performance with reliable supply.
We maintain an extensive stock range supported by technical sales expertise, in-house quality testing and custom engineering capabilities, helping customers source the optical components they need for both development and production programmes.
