A flame scanner collimator, which monitors flames produced by a fossil fuel fired combustion chamber, includes: a substantially cylindrical collimator body defining a hollow portion; a first chamber connected to a second chamber, the first and second chambers defining the hollow portion, the second chamber having a larger diameter than the first chamber; and a plurality of slots each extending in substantially a same direction as a longitudinal axis defining the body. Each slot extends through the body to the first and second chambers to allow cooling/purge air flow therethrough.

What is claimed is: 1. A flame scanner collimator for monitoring flames produced by a fossil fuel fired combustion chamber, comprising: a substantially cylindrical collimator body defining a hollow portion; a first chamber connected to a second chamber, the first and second chambers defining the hollow portion, the second chamber having a larger diameter than the first chamber; and a plurality of slots each extending in substantially a same direction as a longitudinal axis defining the body, each slot extending therethrough the body including interior sidewalls of the body defining the first and second chambers to allow cooling/purge air flow therethrough. 2. The flame scanner collimator of claim 1, wherein each slot includes a lower portion which extends to an upper portion, the lower portion of each slot is disposed substantially on a right side of the longitudinal axis while the upper portion of each respective slot is disposed substantially on a left side of the longitudinal axis. 3. The flame scanner collimator of claim 2, wherein an interface between the lower and upper portions crosses over the longitudinal axis. 4. The flame scanner collimator of claim 3, wherein each of the plurality of slots is substantially parallel with one another and the plurality of slots circumvent a circumference defining the body. 5. The flame scanner collimator of claim 1, wherein each slot is curved having an elongated S-curve to create a vortex for cooling/purge air which flows outside and inside the collimator body, the elongated S-curve slots are configured to initiate air turbulence past a lens disposed in the collimator body. 6. The flame scanner collimator of claim 5, wherein the plurality of slots create the vortex with respect to the cooling/purge airflow via a configuration of opposing first and second edges defining each slot, and a cross section portion of the collimator body intermediate adjacent slots resembles a trapezoid in which the first and second edges define opposing sloping sides of the trapezoid, a portion of the first edge corresponding to an upper portion of the slot and a portion of the second edge corresponding to a lower portion of the slot define a more acute angle compared to a remaining portion of the first and second edges. 7. The flame scanner collimator of claim 6, wherein the portion of the first edge corresponding to the upper portion of the slot initially tapers inwardly toward the second edge as the first edge extends toward the longitudinal axis, and a remaining terminal portion most proximate to the longitudinal axis tapers outwardly substantially normal to an initial portion of the first edge relative to an outer diameter defining the collimator body. 8. The flame scanner collimator of claim 1, wherein the first chamber is configured having a diameter slightly larger than a diameter of the outside diameter of a lens barrel assembly to allow slidable translation of the lens barrel assembly therethrough while maintaining alignment of the lens barrel assembly relative to the collimator body. 9. The flame scanner collimator of claim 8, wherein the first chamber diameter increases toward an end of the collimator body providing a tapered diameter of the first chamber as the first chamber extends toward the end of the collimator body having a guide cylinder thereat, and a remaining portion of the first chamber acts as a lens barrel guide for continued lens barrel sighting alignment during translation of the lens barrel assembly relative to the collimator body. 10. The flame scanner collimator of claim 1, wherein the collimator body integrates an end cap having a guide cylinder to be received in a corresponding guide pipe as a unitary indivisible part. 11. The flame scanner collimator of claim 10, wherein the collimator body is cast of stainless steel. 12. A flame scanner collimator for monitoring flames produced by a fossil fuel fired combustion chamber, comprising: a substantially cylindrical collimator body defining a hollow portion; a first chamber connected to a second chamber, the first and second chambers defining the hollow portion, the second chamber having a larger diameter than the first chamber; a lens barrel assembly slidably disposed in the first chamber of the collimator body; and a biasing member disposed in the second chamber biasing the lens barrel assembly away from the second chamber and allowing translation of the lens barrel assembly in the first chamber. 13. The flame scanner collimator of claim 12, further comprising: a fiber optic cable having a first end and an opposite second end, the first end disposed in one end of the lens barrel assembly engaging corresponding threads thereon; a flat washer slidably disposed within the second chamber and abutting the one end of the lens barrel assembly, the flat washer having the threaded first end of the fiber optic cable extending therethrough; and a threaded locknut threaded onto the threads of the first end of the fiber optic cable to lock the flat washer against the lens barrel assembly. 14. The flame scanner collimator of claim 13, wherein the flat washer includes an outside diameter which is larger than a diameter of the first chamber, larger than a diameter of the biasing member, and smaller than a diameter of the second chamber. 15. The flame scanner collimator of claim 14, wherein the biasing member is a compression spring. 16. The flame scanner collimator of claim 15, further comprising: a lock washer intermediate the flat washer and the locknut. 17. The flame scanner collimator of claim 15, wherein the spring is disposed in the second chamber having one end of the spring abutting the flat washer and an opposite end of the spring abutting an NPT adapter, the NPT adapter retains the spring in the second chamber, the spring compresses the lens barrel assembly away from the NPT adapter secured in the second chamber of the collimator body. 18. The flame scanner collimator of claim 17, wherein the NPT adapter is secured in the second chamber of the collimator body via set screws received through corresponding apertures configured in the collimator body and threaded into respective threaded holes in the NPT adapter. 19. The flame scanner collimator of claim 18, wherein one end of the NPT adapter includes a threaded portion which receives the fiber optic cable therethrough and a corresponding threaded end of a flame scanner assembly. 20. The flame scanner collimator of claim 12, further comprising: a plurality of slots each extending in substantially a same direction as a longitudinal axis defining the body, each slot extending therethrough the body including interior sidewalls of the body defining the first and second chambers to allow cooling/purge airflow therethrough.
