Abstract
A modular microscope can quickly be modified for specific scanning applications. The microscope includes a microscope main body which has slots into which long pass filter modules, dichroic mirror modules, notch filter modules, and LED modules can be selectively placed, removed, and changed out. In some applications, the interchangeable components permit quickly changing between Photoluminescence (PL) and Raman spectroscopy (microscope) systems.

A modular microscope kit, comprising:
- a microscope main body comprising a first portion connected or connectable to at least one objective lens and a second portion connected or connectable to at least one fiber assembly that delivers optical information to a spectrometer,
- wherein the microscope main body includes:
- at least one light emitting diode (LED) port, at least one laser source port,
- and at least one camera port,
- at least one dichroic module slot, positioned in the microscope main body between the first portion and the second portion,
- at least one long pass filter slot, positioned in the microscope main body between the at least one dichroic module slot and the second portion, and
- at least one notch filter slot, positioned in the microscope main body in alignment with the at least one camera port, and
- wherein the microscope main body is configured to provide one or more optical pathways from the at least one light emitting diode (LED) port and the at least one laser source port to one or more of the at least one camera port, the first portion of the microscope main body, and the second portion of the microscope main body;
- at least one LED module that is removably connectable to the at least one LED port of the microscope main body;
- at least one camera module that is removably connectable to the at least one camera port of the microscope main body;
- at least one laser source that is removably connectable to the at least one laser source port of the microscope main body;
- at least one dichroic module that is insertable into and removable from the at least one dichroic module slot in the microscope main body, and has a configuration such that while inserted in the at least one dichroic module slot the at least one dichroic module is positioned to:
- direct, in response to receiving generated LED light from the at least one LED light connected to the at least on LED port, a portion of the generated LED light from the at least one LED module towards and through the first portion of the microscope main body, and
- direct, in response to receiving generated laser light from the at least one laser source connected to the at least one laser source port, a portion of the generated laser light from the at least one laser source, towards and through the first portion of the microscope main body, and
- direct a portion of a reflected light from the first portion of the microscope main body to either the at least one camera module connected to the at least one camera port, or the at least one fiber assembly, via the second portion of the microscope main body;
- at least one notch filter module that is insertable into and removable from the at least one notch filter slot in the microscope main body, wherein:
- the at least one notch filter slot in the microscope main body is configured such that the at least one notch filter module, while inserted in the at least one notch filter slot, is positioned in alignment with the at least one camera module connected to the at least one camera port, and
- the at least one notch filter module is designed to block one or more wavelengths of the generated laser light and to allow other wavelengths of the generated LED light to pass therethrough;
- and
- at least one long pass filter module that is insertable into and removable from the at least one long pass filter module slot in the microscope main body, and has a configuration to block, while inserted in the at least one long pass filter slot, stray light from the at least one laser source from reaching the at least one fiber assembly to which the second portion of the microscope main body is connected.
