Optical system for fluorescence imaging |
| abstract |
Optical systems for DNA sequencing and other assays are described. Microscope designs may include a light source configured to emit an excitation beam and an objective lens disposed to receive the excitation beam, direct the excitation beam to a specimen, and receive emission light emitted by the specimen in response to the excitation beam. A plurality of detection channels includes optics configured to receive at least a portion of the emission light. A first dichroic filter can be disposed to reflect the excitation beam into the objective lens and to transmit the emission light, and a second dichroic filter can be disposed to receive the transmitted emission light, transmit a first portion of the transmitted emission light to a first channel of the plurality of channels, and reflect a second portion of the transmitted emission light to a second channel of the plurality of channels. Imaging or detection performance may further be improved by a reduced angle of incidence between the emission light and some or all of the dichroic filters, and/or by linearly polarizing the excitation beam such that the excitation beam is s-polarized with respect to the first dichroic filter. |
