Claim 1
1 . A camera mount system, comprising: an image sensor; a housing comprising a housing first side and a housing second side opposite the housing first side; an eyepiece in the housing first side; a scope opening in the housing second side; a beam splitter between the eyepiece and the scope opening; one or more optical elements positioned within the housing between the beam splitter and the image sensor; and wherein the beam splitter is configured to split an input optical signal received from the scope opening into an input signal first portion directed to the eyepiece and an input signal second portion directed to the one or more optical elements; wherein the one or more optical elements are configured to direct the input signal second portion from the beam splitter to the image sensor; and wherein the image sensor is configured to capture an image based upon at least an infrared light of the input signal second portion received from the one or more optical elements; wherein the camera mount system further comprises a spacer having a circular outer surface configured to engage a circular inner surface of a mounting collar of the housing at the scope opening, wherein the spacer comprises a non-concentric opening configured to receive an eyepiece of a scope; the circular inner surface of the mounting collar permitting rotation of the circular outer surface of the spacer while the spacer is resident in the mounting collar to achieve boresight alignment; and a clasp of the mounting collar configured, when manually tightened after alignment, to immobilize the spacer to maintain optical-axis alignment. an image sensor; a housing comprising a housing first side and a housing second side opposite the housing first side; an eyepiece in the housing first side; a scope opening in the housing second side; a beam splitter between the eyepiece and the scope opening; one or more optical elements positioned within the housing between the beam splitter and the image sensor; and wherein the beam splitter is configured to split an input optical signal received from the scope opening into an input signal first portion directed to the eyepiece and an input signal second portion directed to the one or more optical elements; wherein the one or more optical elements are configured to direct the input signal second portion from the beam splitter to the image sensor; and wherein the image sensor is configured to capture an image based upon at least an infrared light of the input signal second portion received from the one or more optical elements; wherein the camera mount system further comprises a spacer having a circular outer surface configured to engage a circular inner surface of a mounting collar of the housing at the scope opening, wherein the spacer comprises a non-concentric opening configured to receive an eyepiece of a scope; the circular inner surface of the mounting collar permitting rotation of the circular outer surface of the spacer while the spacer is resident in the mounting collar to achieve boresight alignment; and a clasp of the mounting collar configured, when manually tightened after alignment, to immobilize the spacer to maintain optical-axis alignment.
