Optical Coherence Tomography OCT Imaging System

TRICHROME Series pre-clinical SD-OCT

Ultrahigh resolution and collagen fibre contrast

Simtrum is proud to release TRICHROME  SD-OCT which provides unprecedented spatial resolutions and tissue contrast. It is the highest resolution Optical Coherence Tomography device for preclinical use and is equipped with the unique capability of detecting collagen fiber by capturing their natural colour.


- Ultrahigh axial resolution (2.5 µm in air  and 1.8 µm in water);

- Unique collagen fiber imaging capability  based on entrinsic colour;

- Handheld dermatoscopy for pre-clinical use;

- Quick switch between the objective lens of various magnifications.

Optical coherence tomography (OCT) is a non-invasive imaging technology, that provides real-time and cross-sectional images or fast 3D images of samples. OCT works similar to B-mode ultrasonic imaging. However, spatial resolutions of OCT can be as good as 1-2 μm, which is two orders of magnitude higher than those of ultrasound. The penetration depth of OCT is in the range of 2-3 mm. The non-contact and non-invasive nature makes OCT a perfect tool for diagnosing diseases in mucosa and surface inspection of products.
