Benefits of technology

The patent text is suggesting a way to reduce the angle at which light enters an optical system. By using a lens with a longer working distance, the light is incident at a smaller angle. This can improve the quality of images captured using the optical system.

Problems solved by technology

Disadvantageously, this set up requires the use of filters and a dichroic mirror specific to the specimen being studied.
Further, these filters and mirrors require the use of special materials and significantly increase the cost of the microscope.
Disadvantageously, this set up still requires purchasing costly filters.
Further, it still requires purchasing a variety of costly filters to observe a diverse range of specimens.

Embodiment Construction

[0051]FIG. 1 illustrates one embodiment of the invention. The light source 102 is attached to the fluorescence microscope assembly 100. The light source 102 holds one or more LEDs 110 which excites the fluorescence specimen. In this embodiment multiple LEDs 110 are used. The light source 102 is attached to the microscope via the objective lens assembly 104. The LED mount tube 112 is located coaxially around the objective lens assembly 104. LED mount tube 112 is a tube with a gap along its length. The LED mount tube 112 includes flanges 114 with holes 118 defined through them at each side of the gap. These flanges 114 can be forced apart or together to increase or decrease the size of the gap and thus the internal diameter of the LED mount tube 112, respectively. The light source 102 is seated on the outer surface of the objective lens assembly 104 by forcing the flanges 114 together with a load. In a preferred embodiment the load is applied by running a fastener through the holes 11...

Abstract

Disclosed is an LED fluorescence microscope without a need for light filters or dichroic mirrors and a method for using the same. The light source for this microscope is made of one or more LEDs directly illuminating the specimen 306 being observed without the use of any light filters or dichroic mirrors.

Description

RELATED APPLICATIONS[0001]This application is related under 35 USC 120 to the patent application entitled, Magnetophoresis System for Separation of Biological Particles, Ser. No. 15 / 135,415, filed on Apr. 21, 2016, which in turn was related under 35 USC 119 to Spanish provisional application, serial no. P201500574, filed on Jul. 31, 2015, both which are incorporated herein by reference.BACKGROUND[0002]The invention relates to the field of microscopes specially adapted to specific functions and, in particular, to CPC class G02B (Optical Elements Systems or Apparatus) and / or G02F (Devices or Arrangements, Optical Operation).[0003]A known fluorescence microscope described in U.S. Pat. No. 3,860,813 involves passing light from the light source through an excitation filter to obtain an excitation wavelength. This wavelength is then reflected by a dichroic mirror through the objective lens to the specimen. The fluorescence band is then collected through the objective lens and passes throu...
