The influence of uniaxial mechanical pressures (σ_m ≤ 200 bar) on the spectral (300-800 nm) and temperature (77-300 K) dependences of the refractive indices n_{i}, the birefringence Δn_{i} and the phase transition point in ammonium sulfate crystals are studied. It is established that the uniaxial pressure does not change character of the dispersion dn_{i}/dλ, but only its value λ The shift of the phase transition in ammonium sulfate under the uniaxial mechanical pressure is analyzed.
