Optical Spectrometers & Spectroscopy Accessories
Optical spectrometers are used to characterise thin film samples and solutions via optical spectroscopy (often referred to as UV-Vis spectroscopy). Within a spectrometer, a dispersive element (for example, a prism) splits incoming light into its integrant wavelength components. This light is then directed onto an optical sensing element, which measures the intensity of light at each wavelength. By directing a calibrated light source into a spectrometer after it has passed through a material, or reflected off a sample, you can directly measure how your sample interacts with light. You can use this information to indirectly measure other material properties, such as the concentration of a molecule in your sample.
Optical spectroscopy is a versatile technique, which is fast and easy to do. Through even the simplest absorbance measurement, you can learn a lot about your sample, such as molecular composition, concentration, or photo-stability of your sample. Optical spectroscopy is used across the sciences to characterise a wide range of samples including measuring material properties of optoelectronic materials, tracking bacterial culture growth and measuring fluorescent or photoluminescent materials.
Our low price spectrometers have a small lab footprint and come with accompanying software to enable fast integration with any lab. The modular design of the spectrometer along with the complementary accessories, make it possible to adapt the spectrometer set up for your specific needs. We have created the Ossila Optical Spectrometer to facilitate optical spectroscopy measurements for as many researchers as possible. These include absorption, photoluminescence and reflectance measurements.
The Ossila Optical Spectrometer has a range of low price complementary equipment and accessories. For the best value, we recommend our complete optical spectroscopy bundle includes a spectrometer, broadband white light source, UV light source, cuvette holder, four port transmission holder, two SMA optical fibres, an optical mirror, and a breadboard plate. This would enable you to do absorbance, reflectivity, and photoluminescence measurements. Available now for a discounted price with free world shipping and spectroscopy software.

Optical Spectrometer
The Ossila Optical Spectrometer is compact, low price, and suitable for taking research-grade optical spectroscopy measurements of thin films or solutions. Controllable via our free software or with simple serial commands, the spectrometer can be set up and adopted into any lab. Covered by our two-year warranty and eligible for free worldwide shipping.

Broadband White Light Source
USB-C powered LED light source which exhibits light between 360-900 nm. Ideal light source for measuring transmission or absorbance. Optimised to be used with the Ossila Optical Spectrometer but can be used as a light source for other spectrometers. Align with our optical breadboard or use with optical fibers.

Cuvette Holder
Compatible with any standard 10 mm path length cuvettes for absorption, fluorescence, and transmission measurements on solutions. Connect optical fibers for direct transmission through the solution or align with the spectrometer for free air measurement. Removable plugs allow you to measure fluorescence at 90° angles from the illumination source.

Spectroscopy Transmission Holder
These sample holders are designed to hold rigid or flexible substrates up to maximum 6.5 mm thickness. Retractable clamp allows you to fix your samples in place during spectroscopy measurements. Available with 2-ports for direct transmission or 4-ports for additional reflectivity or photoluminescence measurements.

UV Light Source
USB-C powered UV LED light source with a peak wavelength at 370 nm. This light source is an excitation source for photoluminescence measurements. Optimised to be used with the Ossila spectrometer. Can be aligned so light travels through air or can be used with optical fibres.

Optical Fiber
Our optical fibres connect directly to our sample holders, light sources, and optical spectrometers. These fibres aid light transport between components, reducing optical losses, and negating the need for alignment. Fibre length 1 m with 400 µm core.

Optical Breadboard Plate
This compact optical breadboard can be used to set up an optical bench on any worktop or desk space. Optical and measurement equipment can be fixed in place to ensure position continuity between measurements. Made of anodized aluminium, this breadboard is rigid but lightweight.

Spectrometer Case
Specially designed protective case for the Ossila Optical Spectrometer. It is important that the spectrometer stays in the same place for the course of a measurement. The spectrometer case can be fixed onto the Optical Breadboard at the various mounting points to ensure consistent position. The case also provides some protection for the spectrometer against falling or physical damage.

Quartz Cuvettes
Quartz cuvettes are ideal for taking spectroscopy measurements on solutions. Quartz has high levels of transmission of visible light, so should not interfere with optical spectroscopy measurements, such as absorption and photoluminescence. There are various different cuvettes you can get depending on the solution, with variable path length, volume or transmission wavelength windows.

Optical Mirror (20 mm x 15 mm)
This optical mirror is a silver mirror coated with SiO2 with reflectivity of over 0.96 above 550 nm. This is a reference sample for reflectivity measurements, as it should represent a completely specular surface.

Ultra-flat Quartz Coated Glass Substrates
Quartz-coated glass substates are perfect for taking spectroscopy measurements on thin films. Quartz has high levels of transmission of visible light, so should not interfere with optical spectroscopy measurements, such as absorption and photoluminescence. These substrates are extremely smooth to enable you to make smooth, uniform films.
