A light source module includes a plurality of light sources mounted in at least one block. The block includes a mating surface for mating the at least one block to an adjacent block, and a plurality of mounting pads for respectively mounting the plurality of light sources, said mounting pads occupying multiple planes in a direction normal to a direction of light emission from the light sources. The mating surface is parallel to the direction of light emission from the light sources. Multiple blocks may be combined by joining the mating surface of a first block with a protrusion extending beyond the mating surface of an adjacent block. When the blocks are combined in this fashion, the mounting pads positioned in the multiple planes overlap in a viewpoint direction along an axis normal to the mounting pads. In this manner, light sources do not impede light emission from adjacent light sources.

A gas analyzer and related methods are for measuring a concentration of a component of a gas mixture. The gas analyzer includes a gas cell defining an overall volume for housing the gas mixture, a gas inlet and a gas outlet, a light source that emits a light beam into the gas cell, and a light detector that detects a portion of the light of the light beam that has propagated through the gas mixture, the concentration of the component of the gas mixture being determined based on the portion of the light beam detected by the light detector. The gas cell defines an optical volume for travel of the light beam within the gas cell, and the optical volume comprises at least a portion of the overall volume and is configured to suppress turbulent flow of the gas mixture within the optical volume to reduce optical noise generated by the gas mixture.
