Circular dichroism spectrometer is an instrument used for determining the secondary protein structure. Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light.[1][2] Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism for spin angular momentum.

According to HJ Research's Report, Global Circular dichroism spectrometer market was valued at 62.03 Million US$ in 2018 and is projected to reach 90.51 Million US$ by 2024, at a CAGR of 6.5% during the forecast period

Global spectrometry market increased from $7.8 billion in 2011 to $8.5 billion in 2012 and is expected to reach $15.7 billion in 2019, a compound annual growth rate (CAGR) of 11.7% for the forecast period of 2012 to 2017. Growth in the spectroscopy market is occurring in the bio- and health care-related fields, in particular.
In addition to global growth, the spectroscopy market continues to expand largely due to the technological developments and demand from pharmaceutical and biotechnology, environmental, and food and beverage industries. From $13.5 billion in 2015, this market is expected to hit $15.6 billion by 2020. North America alone will account for nearly $6 billion. 
The spectroscopy market evolution can be attributed to a rising interest in eco-friendly technologies and increased environmental concerns, for which spectroscopic instruments can play a key role.
