| Abstract: | The design and mathematical model of a reflective type optical gas sensor is presented. Light source is radiated at an incident angle for 10 cm gas cell with an internal diameter of 0.4 cm. At an incident angle of 1o, optical path length obtained is 342.7886 cm, at 27o incident angle, optical path length is 10.4926 cm and at an incident angle of 28 o , optical path length is 9.9631 cm. The model is most efficient at lower incident angles, precisely between (1o and 27o ). Effects of variation in diameter and length of gas cell are also demonstrated |
