Commercialisation of a high speed, digital confocal microscope
Lead Research Organisation:
University of Leicester
Department Name: Cell Physiology and Pharmacology
Abstract
We have developed a high speed digital confocal microscope that uses a digital micro-mirror device developed originally by Texas Instruments for projectors and televisions. The microscope allows optical sectioning of fluorescent specimens leading to acquisition of high quality images at faster speeds. We have identified several aspects of the current configuration that need to be improved before going to market. In collaboration with Prior Scientific Ltd., we will contract a professional optical engineer to scrutinise our design and then work collaboratively with Prior to implement and evaluate changes. We will improve the coupling efficiency of the light source, remove unwanted stray light and optimise the configuration of optical components. This will improve the image quality, reduce cost and simplify manufacture. Our aim is to develop a device that can be bolted on to existing imaging systems to produce a high quality, high speed but low cost device for use in biological research.

Description | This award was a follow on fund award that emerged from an earlier grant (BB/E00461X/1 ). We worked with a company called Prior Scientific. Although progress has been slow, and much of the work has taken place after the grant officially ended, we are now in negotiations to licence the technology and we hope that they will develop a prototype in the next few months. if this is succesful, we may end up with a commercial product that will be of use to the general imaging community |
Exploitation Route | As part of this grant, we developed a method that allows the use of digital micromirrors in imaging. This is patented and although our own use is to develop a digital form of microscope, the patent scope is broad enough to impact on other areas of imaging. |

Description | We have published a paper that describes the work that lead to the development of this microscope and a patent that protects the IP behind it. We have worked with a commercial partner and we are now in the process of developing a prototype with the view to licencing the technology. Since writing this, we now have a nice prototype for demonstration and we have combined this technology with new technology we have developed to demonstrate that this system can be adapted for use as a super resolution microscope. A patent has now been awarded in the US. |

Title | IMPROVED OPTICAL ARRANGEMENT |
Description | The present disclosure relates to an improved optical arrangement for an optical imaging system or the like, comprising: an optical device; a digital micromirror device having a plurality of individually addressable micromirrors; a convex mirror; and a concave mirror concentric to the convex mirror. The convex mirror and the concave mirror define an optical triplet which is located in an optical path with the digital micromirror device and the optical device. The concave mirror comprises two concave mirror sections, one or both concave mirror sections being moveable relative to the convex mirror so as to control an image mapping between the digital micromirror device and the optical device. |
