Diagnostic instruments having multiple illumination sources and methods thereof
A method of operating a diagnostic instrument includes illuminating an imaging location of the diagnostic instrument with first light having a first spectrum for a first period and capturing a first image of the imaging location illuminated by the first light. The method further includes illuminating the imaging location of the diagnostic instrument with second light having a second spectrum for a second period, the second spectrum being more destructive to a chemical configured to be received in the diagnostic instrument than the first spectrum; and capturing a second image of the imaging location illuminated by the second light. Other methods and diagnostic instruments are disclosed.
1 . A method of operating a diagnostic instrument, comprising:
illuminating an imaging location of the diagnostic instrument with first light having a first spectrum for a first illumination period;
capturing a first image of the imaging location illuminated by the first light;
analyzing the first image;
illuminating the imaging location of the diagnostic instrument with second light in response to the analyzing, the second light having a second spectrum for a second illumination period, the second spectrum being more destructive to a chemical received in the diagnostic instrument than the first spectrum; and
capturing a second image of the imaging location illuminated by the second light.
2 . The method of claim 1 , wherein the analyzing comprises identifying one or more items in the first image and determining whether the one or more items will be damaged by exposure to the second light.
3 . The method of claim 1 , wherein the analyzing comprises identifying one or more items in the first image and determining an extent to which the one or more items will be damaged by exposure to the second light.
4 . The method of claim 1 , wherein the analyzing comprises determining the second illumination period.
5 . The method of claim 1 , wherein the first light is infrared light or near infrared light.
6 . The method of claim 1 , wherein the first light includes a wavelength of from 900 nm to 1,100 nm.
7 . The method of claim 1 , wherein the second light is ultraviolet light.
8 . The method of claim 1 , wherein the second light includes a wavelength of from 355 nm to 375 nm.
9 . The method of claim 1 , wherein the second illumination period is about 100 ms.
10 . The method of claim 1 , wherein the imaging location includes a component configured to process a specimen.
11 . The method of claim 1 , comprising receiving a specimen, wherein the specimen is located at the imaging location.
12 . A method of operating a diagnostic instrument, comprising:
illuminating an imaging location of the diagnostic instrument with first light having a first spectrum for a first illumination period;
capturing a first image of the imaging location illuminated by the first light;
illuminating the imaging location of the diagnostic instrument with second light having a second spectrum for a second illumination period, wherein the second illumination period is less than 150 ms, the second spectrum being more destructive to a chemical received in the diagnostic instrument than the first spectrum; and
capturing a second image of the imaging location illuminated by the second light.
13 . A method of operating a diagnostic instrument, comprising:
illuminating an imaging location of the diagnostic instrument with first light having a first spectrum for a first illumination period;
capturing a first image of the imaging location illuminated by the first light;
analyzing the first image;
determining, based on the analyzing, a second light to illuminate the imaging location, the second light having a second spectrum, the second spectrum being more destructive to a specimen received in the diagnostic instrument than the first spectrum;
determining, based on the analyzing, a second illumination period that the second light is to illuminate the imaging location, the second illumination period being less than the first illumination period;
illuminating the imaging location with the second light for the second illumination period; and
capturing a second image of the imaging location illuminated by the second light.
14 . The method of claim 13 , wherein the analyzing comprises identifying one or more items in the first image and determining whether the one or more items will be damaged by exposure to the second light.
15 . The method of claim 13 , wherein the analyzing comprises identifying one or more items in the first image and determining an extent to which the one or more items will be damaged by exposure to the second light.
16 . The method of claim 15 , wherein the one or more items are at least one specimen.
17 . The method of claim 13 , wherein the first light is infrared light or near infrared light.
18 . The method of claim 13 , wherein the second light is ultraviolet light.
19 . A diagnostic instrument, comprising:
an imaging location;
a first illumination source configured to illuminate the imaging location with first light having a first spectrum for a first period;
a second illumination source configured to illuminate the imaging location with second light having a second spectrum for a second period, wherein the second spectrum is more destructive to a specimen receivable in the diagnostic instrument than the first spectrum and the second period is less than the first period;
an imaging device configured to capture a first image of the imaging location illuminated by the first light and a second image of the imaging location illuminated by the second light; and
a computer configured to execute instructions to:
analyze the first image;
determine the second spectrum in response to analyzing the first image; and
determine the second period in response to analyzing the first image.
20 . The diagnostic instrument of claim 19 , wherein the computer is configured to identify one or more items in the first image and determine whether the one or more items will be damaged by exposure to the second light.
