Lighting systems and methods of using lighting systems for in vitro potency assay for photofrin
First Claim
1. A lighting system comprising:
- a lamp housing including a wall, a lamp, and a light-port, wherein the light-port is located within the wall, and wherein broad spectrum light from the lamp exits the lamp housing through the light-port;
a first lens to collimate the broad spectrum light that exits the lamp housing through the light-port;
an infrared absorbing filter to pass a first portion of the collimated broad spectrum light and absorb infrared light of the broad spectrum light that passes through the light-port and that is collimated by the first lens, wherein the first portion of the collimated broad spectrum light comprises a second portion of the collimated broad spectrum light;
an optical filter to pass the second portion of the collimated broad spectrum light after the first portion of the collimated broad spectrum light reaches the optical filter;
a second lens to disperse the second portion of the collimated light that passed through the optical filter, wherein a position of the second lens is adjustable in at least one of a direction parallel to the wall and a direction perpendicular to the wall;
a shelf including a shelf top perpendicular to the wall; and
a lens slider removably attached to the shelf top, wherein the second lens is removably attached to the lens slider, wherein the lens slider includes a first hole for passing the dispersed second portion of the collimated light that passed through the second lens, wherein the shelf includes a second hole for passing the dispersed second portion of the collimated light that passed through the second lens, and wherein at least a portion of the first hole is above or below at least a portion of the second hole.

Abstract
Presently disclosed is a lighting system and methods of using the lighting system for in vitro potency assay for photofrin. The lighting system includes a lamp housing, a first lens, an infrared absorbing filter, an optical filter, and a second lens. The lamp housing includes a lamp and a light-port. In operation, broad spectrum light from the lamp exits the lamp housing by passing through the light-port. The first lens then collimates the broad spectrum light that exits the lamp housing through the light-port. The infrared absorbing filter then passes a first portion of the collimated broad spectrum light to the optical filter and absorbs infrared light of the broad spectrum light. The optical filter then passes a second portion of the collimated broad spectrum light to the second lens. The second lens then disperses the second portion of the collimated light to provide uniform irradiation of a cell culture plate. A method of using the lighting system for studying a photosensitizer is also disclosed.
