A laser capture microdissection lift-off substrate comprising a transparent thermoplastic film is incorporated into substrate which may take the form of a cap or other structure associated with an analysis vessel or which may be used with a holder or other element of a LCM tissue sample transfer apparatus. The thermoplastic lift-off substrate film is held in a fixed position on the substrate which may be relative to a feature of a biological analysis vessel. The film may be affixed to a substrate which is a structure which goes into the vessel such that the sample is held in a fixed position relative to an observation port on the vessel.
摘要:
A dispersion compensation delay line is added to a synchronously pumped fiber Raman ring oscillator to generate subpicosecond pulses. A pair of spaced gratings form the delay line. An interference filter is used as a bandwidth limiting tuning element to provide a good quality short pulse. An integrated design eliminates the discrete optical elements by using only an optical fiber and an optical fiber coupler.

In a laser amplifier a high efficiency pumping scheme mode matches the TEMOO laser mode volume with a plurality of linearly spaced laser diode pumping sources positioned along a lateral side of a block of laser material. The optical path within the block is configured in a tightly folded zig-zag configuration. Pump radiation from the diode pumping sources is collimated by an optical fiber end the fold angle is selected to mode match the pump radiation to the mode volume.A laser oscillator is followed by one or more cascaded amplifier stages including a block of laser material arranged in a tightly folded zig-zag configuration. Pump radiation from the diode pumping sources is collimated by an optical fiber and the fold angle is selected to mode match the pump radiation to the mode volume.
摘要:
The present invention generally discloses an extraction system that provides a locale for fluid processing and extraction on a post-microcapture transfer film. The extraction system includes a transfer film carrier and an extraction device forming a reservoir. The extraction system selectively excludes regions of the transfer film from the reservoir to advantageously reduce contamination due to matter adhered to the transfer film by non-specific transfer.
